If there are more than 17 digits to the left of the decimal, Mathcad displays
zeros for the remaining digits, but only the first 16 digits are accurate. For

Results display as fractions. You can control whether mixed numbers are
used.
The default is "General."
Number of decimal places (แ แแแฝแแแแแแแแแแแแ)
Normally, this controls the number of digits displayed to the right of the decimal
point, assuming that "Show trailing zeros" is checked. However, if N is the
number of digits to the left of the decimal point, then at most 17 โ N digits can
be displayed to the right of the decimal point, regardless of the setting of
"Number of decimal places." This option affects only the display. Calculations
occur with full precision no matter how you decide to display the result.
For example, the number .126125 is displayed as follows:
Number of
decimal places
Result in
decimal format
2 .13
3 .126
4 .1261
5 .12613
6 .126125
The number of decimal places must be between 0 and 17 inclusive. The default
is 3.

Show trailing zeros (แแแแแแ แถ แแแแแแแผแแแแแแแแแแแแแ)
Controls whether trailing zeros display to the right of the decimal point to fulfill
the current choice of "Number of decimal places."
For example, if "Number of decimal places" is 3, then:
1.5 "Show trailing zeros" is unchecked Displays as 1.5
1.5 "Show trailing zeros" is checked Displays as 1.500
If a result has more than 17 digits total and "Show trailing zeros" is checked,
Mathcad displays 17 digits followed by zeros until there are as many digits to the
right of the decimal point as specified by "Number of decimal places." The
exception is when "General" format is selected as the Format scheme. If
"General" is selected and "Show trailing zeros" is checked, Mathcad does not
display zeros beyond 17 digits total, regardless of "Number of decimal places"
specified. For example:
Number

12.345678 Engineering Decimal places = 4 12.3457 x 100
The default is "Show trailing zeros" turned off.
Exponential threshold (แแแแแแ แถ แแแทแแแแแ)
When "General" format is selected, controls whether you see a number displayed
in exponential notation. Results of magnitude greater than 10n
or smaller than
10โn
, where n is the exponential threshold, are displayed in exponential notation.

The exponential threshold must be between 0 and 15 inclusive. The default is 3.
This means that all numbers outside the intervals [.001, 1000] and [โ1000,
โ.001] are shown in exponential notation.
For binary, octal, and hexadecimal numbers, results of magnitude greater than
bn
or smaller than bโn
, where b is the display radix and n is the exponential
threshold, are displayed in exponential notation.
Show exponents as Eยฑ000 (แแแแแแ แถ แแแทแแแแแแแถ Eยฑ000)
When either "Scientific" or "Engineering" format is selected as the Format and
this option is checked, the result is displayed using E notation. For example:
Scientific Format:
23.4556 = 2.346 ร 101
Scientific Format with exponents in E notation:
23.4556 = 2.346 E+001
The default is "Show exponents as Eยฑ000" turned off.
Use mixed numbers (แแแแแแแธแแแแแ แแแปแปแ)
When "Fraction" is selected as the Format and this option is checked, the result
is displayed as a mixed number. For example:

The default is "Use mixed numbers" turned off.
Level of accuracy (แแแแทแแแถแแแนแแแแผแ)
When "Fraction" is selected as the format, controls how close the fraction
approximation is to the decimal value. The higher the accuracy, the closer an
approximation. The default is 12.

The default is unchecked.
If a nested array is displayed as a table, you can temporarily expand an element
by right-clicking on the table and choosing Down One Level from the menu.
Imaginary value
Controls whether computed results having an imaginary part are displayed using
"i" or "j."
You can continue to use either "i" or "j" when you enter an imaginary number.
You can only set this option when a particular result is not selected. Click in a
blank part of your worksheet, then choose Result from the Format menu.
The default is "i."
Radix
Controls whether a number is displayed as binary, octal, hexadecimal, or decimal.
The default is decimal.
Binary, Hexadecimal, and octal numbers are followed by the letter "b," "h," or "o"
respectively so you can readily distinguish them from decimal numbers. (Mathcad
does not reliably show hexadecimal or octal numbers of magnitude greater than
231
.)
