Conversion of Number Systems
Number System is a method of representing Numbers on the Number Line with the help of a set of Symbols and rules. These symbols range from 0-9 and are termed as digits. Number System is used to perform mathematical computations ranging from great scientific calculations to calculations like counting the number of Toys for a Kid or Number chocolates remaining in the box. Number Systems comprise of multiple types based on the base value for its digits.
Numbering system, binary number system, octal number system, decimal number system, hexadecimal number system.
Code conversion, Conversion from one number system to another, floating point numbers
Digital computers represent data by means of an easily identified symbol called a digit. The data may
contain digits, alphabets or special character, which are converted to bits, understandable by the computer.
In Digital Computer, data and instructions are stored in computer memory using binary code (or
machine code) represented by Binary digIT’s 1 and 0 called BIT’s.
The number system uses well-defined symbols called digits.
Number systems are classified into two types:
o Non-positional number system
o Positional number system
Computers only deal with binary data (0s and 1s), hence all data manipulated by computers must be represented in binary format.
Machine instructions manipulate many different forms of data:
Numbers:
Integers: 33, +128, -2827
Real numbers: 1.33, +9.55609, -6.76E12, +4.33E-03
Alphanumeric characters (letters, numbers, signs, control characters): examples: A, a, c, 1 ,3, ", +, Ctrl, Shift, etc.
So in general we have two major data types that need to be represented in computers; numbers and characters

• INTRODUCTION:
A set of values used to represent different quantities is known as NUMBER SYSTEM.
For example-
A number can be used to represent the number of student in a class or number of viewers watching a certain TV program etc.
• TYPES OF NUMBER SYSTEM:
Number systems are four types,
1. DECIMAL NUMBER SYSTEM,
2. BINARY NUMBER SYSTEM,
3. OCTAL NUMBER SYSTEM,
4. HEXADECIMAL NUMBER SYSTEM,
DECIMAL NUMBER SYSTEM:
The number system that we used in our day to day life is the decimal number system.
Decimal number system has base 10 as it uses ten digits from 0 to 9.
EXAMPLE-(234)10
BINARY NUMBER SYSTEM:
Binary number system uses two digits 0&1.
Its base is 2.
A combination of binary numbers may be used to represent different quantities like 1001.
Example –
(1001)2,
(100)2,
OCTAL NUMBER SYSTEM:

Its base is 16.
Each digit of this number system represents a power of 8.
Example-
(6D) 16,
(A3)16,
CONVERSION METHOD:
There are two methods used most frequently to convert a number in a particular base to another base.
Remainder method,
Expansion method,
REMAINDER METHOD:
This method is used to convert a decimal number to its equivalent value in any other base.
The following steps are to be followed by this method:
Divide the number by the base and note the remainder.
Divide the quotient by the base and note the remainder.
Repeat step 2 until the quotient cannot be divided further. That is, the quotient become to smaller than divisor.
The sequence of remainder starting from last generated 1 prefix by undivided quotient is the converted number.
EXPANSION METHOD:
This method can be applied to convert any number in any base to its equivalent in base 10.
During expansion, the base of the number is sequentially raised to start with 0 and is incremented by one for every digit that occurs in the binary number.

What is the Number Line?
A Number line is a representation of Numbers with a fixed interval in between on a straight line. A Number line contains all the types of numbers like natural numbers, rationals, Integers, etc. Numbers on the number line increase while moving Left to Right and decrease while moving from right to left. Ends of a number line are not defined i.e., numbers on a number line range from infinity on the left side of the zero to infinity on the right side of the zero.
Positive Numbers: Numbers that are represented on the right side of the zero are termed as Positive Numbers. The value of these numbers increases on moving towards the right. Positive numbers are used for Addition between numbers. Example: 1, 2, 3, 4, …
Negative Numbers: Numbers that are represented on the left side of the zero are termed as Negative Numbers. The value of these numbers decreases on moving towards the left. Negative numbers are used for Subtraction between numbers. Example: -1, -2, -3, -4, …
Number and Its Types
A number is a value created by the combination of digits with the help of certain rules. These numbers are used to represent arithmetical quantities. A digit is a symbol from a set 10 symbols ranging from 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. Any combination of digits represents a Number. The size of a Number depends on the count of digits that are used for its creation.
For Example: 123, 124, 0.345, -16, 73, 9, etc.
Types of Numbers
Numbers are of various types depending upon the patterns of digits that are used for their creation. Various symbols and rules are also applied on Numbers which classifies them into a variety of different types:
Number and Its Types
1. Natural Numbers: Natural Numbers are the most basic type of Numbers that range from 1 to infinity. These numbers are also called Positive Numbers or Counting Numbers. Natural Numbers are represented by the symbol N.
Example: 1, 2, 3, 4, 5, 6, 7, and so on.
2. Whole Numbers: Whole Numbers are basically the Natural Numbers, but they also include ‘zero’. Whole numbers are represented by the symbol W.
Example: 0, 1, 2, 3, 4, and so on.
3. Integers: Integers are the collection of Whole Numbers plus the negative values of the Natural Numbers. Integers do not include fraction numbers i.e. they can’t be written in a/b form. The range of Integers is from the Infinity at the Negative end and Infinity at the Positive end, including zero. Integers are represented by the symbol Z.
Example: ...,-4, -3, -2, -1, 0, 1, 2, 3, 4,...

Hardy-Ramanujan number
1729 is the natural number following 1728 and preceding 1730. It is a taxicab number, and is variously known as Ramanujan's number and the Ramanujan-Hardy number, after an anecdote of the British mathematician G. H. Hardy when he visited Indian mathematician Srinivasa Ramanujan in hospital. He related their conversation:
I remember once going to see him when he was ill at Putney. I had ridden in taxi cab number 1729 and remarked that the number seemed to me rather a dull one, and that I hoped it was not an unfavourable omen. "No," he replied, "it is a very interesting number; it is the smallest number expressible as the sum of two cubes in two different ways."

-Srinivasa Ramanujan
A number system is defined as a system of writing to express numbers. It is the mathematical notation for representing numbers of a given set by using digits or other symbols in a consistent manner. It provides a unique representation of every number and represents the arithmetic and algebraic structure of the figures. It also allows us to operate arithmetic operations like addition, subtraction and division.

Fibonacci Sequence .
The Fibonacci Sequence is a definite pattern that can begin with either 0, 1 or 1, 1. The sequence is generated by adding the previous terms, so that 0 +1 equals 1, 1+1 equals 2, 2 + 1 equals 3, 2 + 3 equals 5, 5 + 3 equals 8, 8 + 5 equals 13, 13 + 8 equals 21, 21 + 13 equals 34, 34 + 21 equals 55, and so on. Fibonacci can be found in in every domain such as nature, art, infrastructure ,humans etc. .
Golden ratio, also known as the golden section, golden mean, or divine proportion, in mathematics, the irrational number (1 + Square root of√5)/2, often denoted by the Greek letter ϕ or τ, which is approximately equal to 1.618.
It is the ratio of a line segment cut into two pieces of different lengths such that the ratio of the whole segment to that of the longer segment is equal to the ratio of the longer segment to the shorter segment.
The digestive system of the human body comprises a group of organs working together to convert food into energy for the body. Human Digestive System and Nutrition involve the intake of food by an organism and its utilization for energy. This is a vital process which helps living beings to obtain their energy from various sources. The food which we eat undergoes much processing before the nutrients present in them are utilized to generate energy. This processing is known as digestion. The digestion process involves the alimentary canal along with various accessory organs and organ systems. In humans, the process is quite simple due to our monogastric nature. This means that we have a one-chambered stomach, unlike other animals such as cows, which have four chambers.

2. Conversion between numbers systems is quite an
easy task. Any number from any number system
can be converted to other number systems with the
help of certain methods that will be discussed in
next slides:
4. Decimal Numbers are represented with digits
0-9 and with base 10. Conversion of a number
system means conversion from one base to
another. Following are the conversion of the
Decimal Number System to other Number
Systems:
5. Decimal numbers are represented in base 10, but
the binary numbers are of base 2. Hence, to
convert a decimal number to binary number, the
base of that number is to be changed. Follow the
steps given here :
Decimal to Binary Conversion:
6. •Step 1: Divide the Decimal Number with the base of the number
system to be converted to. Here the conversion is to binary, hence
the divisor will be 2.
•Step 2: The remainder obtained from the division will become the
least significant digit of the new number.
•Step 3: The quotient obtained from the division will become the next
dividend and will be divided by base i.e. 2.
•Step 4: The remainder obtained will become the second least
significant digit i.e. it will be added in the left of the previously
obtained digit.
7. Now, the steps 3 and 4 are repeated until the
quotient obtained becomes 0, and the remainders
obtained after each iteration are added to the left
of the existing digits.
After all the iterations are over, the last obtained
remainder will be termed as the Most Significant
digit.
8.
9. Octal Numbers are represented in base 8.
Hence, to convert a decimal number to octal
number, the base of that number is to be
changed. Follow the steps given here :
Decimal to Octal Conversion:
10. • Step 1: Divide the Decimal Number with the base of the number system to
be converted to. Here the conversion is to octal, hence the divisor will be 8.
• Step 2: The remainder obtained from the division will become the least
significant digit of the new number.
• Step 3: The quotient obtained from the division will become the next
dividend and will be divided by base i.e. 8.
• Step 4: The remainder obtained will become the second least significant
digit i.e. it will be added in the left of the previously obtained digit.
Now, the steps 3 and 4 are repeated until the quotient obtained becomes 0,
and the remainders obtained after each iteration are added to the left of the
existing digits.
11.
12. Hexadecimal Numbers are represented in base
16. Hence, to convert a decimal number to
hexadecimal number, the base of that number is
to be changed. Follow the steps given here :
Decimal to Hexadecimal
Conversion
13. • Step 1: Divide the Decimal Number with the base of the number system to
be converted to. Here the conversion is to Hex hence the divisor will be 16.
• Step 2: The remainder obtained from the division will become the least
significant digit of the new number.
• Step 3: The quotient obtained from the division will become the next
dividend and will be divided by base i.e. 16.
• Step 4: The remainder obtained will become the second least significant
digit i.e. it will be added in the left of the previously obtained digit.
Now, the steps 3 and 4 are repeated until the quotient obtained becomes 0, and
the remainders obtained after each iteration are added to the left of the
existing digits.
16. Binary Numbers are represented with digits 0
and 1 and with base 2. Conversion of a
number system means conversion from one
base to another. Following are the conversion
of the Binary Number System to other
Number Systems:
17. Binary numbers are represented in base 2 but the decimal numbers
are of base 10. Hence, to convert the binary number into a decimal
number, the base of that number is to be changed. Follow the steps
given below:
•Step 1: Multiply each digit of the Binary number with the place
value of that digit, starting from right to left i.e. from LSB to
MSB.
•Step 2: Add the result of this multiplication and the decimal
number will be formed.
Binary to Decimal Conversion
19. Binary numbers are represented in base 2 but the octal
numbers are of base 8. Hence, to convert the binary number
into octal number, the base of that number is to be changed.
Follow the steps given below:
•Step 1: Divide the binary number into groups of three
digits starting from right to left i.e. from LSB to MSB.
•Step 2: Convert these groups into equivalent octal digits.
Binary to Octal Conversion:
21. Binary numbers are represented in base 2 but
the Hexadecimal numbers are of base 10.
Hence, to convert the binary number into Hex
number, the base of that number is to be
changed. Follow the steps given here:
Binary to Hexadecimal
Conversion
22. •Step 1: Divide the binary number into groups of
four digits starting from right to left i.e. from
LSB to MSB.
•Step 2: Convert these groups into equivalent hex
digits.
25. Octal Numbers are represented with digits 0-7 and
with base 8. Conversion of a number system means
conversion from one base to another. Following are
the conversions of the Octal Number System to other
Number Systems:
26. Octal numbers are represented in base 8, but the decimal numbers
are of base 10. Hence, to convert an octal number to a decimal
number, the base of that number is to be changed. Follow the
steps given below:
•Step 1: Multiply each digit of the Octal number with the place
value of that digit, starting from right to left i.e. from LSB to
MSB.
•Step 2: Add the result of this multiplication and the decimal
number will be formed.
Octal to Decimal Conversion
28. Octal numbers are represented in base 8, but the binary numbers
are of base 2. Hence, to convert an octal number to a binary
number, the base of that number is to be changed. Follow the
steps given below:
•Step 1: Write each digit of the octal number separately.
•Step 2: Convert each digit into an equivalent group of three
binary digits.
•Step 3: Combine these groups to form the whole binary
number.
Octal to Binary Conversion
30. Octal numbers are represented in base 8, but the
hexadecimal numbers are of base 16. Hence, to
convert an octal number to a hex number, the base
of that number is to be changed. Follow the steps
given here :
Octal to Hexadecimal
Conversion
31. • Step 1: We need to convert the Octal number to Binary first. For that,
follow the steps given in the above conversion.
• Step 2: Now to convert the binary number to Hex number, divide the
binary digits into groups of four digits starting from right to left i.e. from
LSB to MSB.
• Step 3: Add zeros prior to MSB to make it a proper group of four
digits(if required)
• Step 4: Now convert these groups into their relevant decimal values.
• Step 5: For values from 10-15, convert it into Hex symbols i.e. from A-F
34. Hex Numbers are represented with digits 0-9 and
with letters A-F and with base 16. Conversion of a
number system means conversion from one base
to another. Following are the conversions of the
Hexadecimal Number System to other Number
Systems:
35. Hexadecimal numbers are represented in base 16 but the decimal numbers are
of base 10. Hence, to convert a hexadecimal number to a decimal number, the
base of that number is to be changed. Follow the steps given below:
• Step 1: Write the decimal values of the symbols used in the Hex number i.e.
from A-F
• Step 2: Multiply each digit of the Hex number with its place value. starting
from right to left i.e. LSB to MSB.
• Step 3: Add the result of multiplications and the final sum will be the
decimal number.
