The document describes extensions made to native JavaScript numbers through the Number Prototype. It provides 1) compatibility with ObjectRange through a succ method, 2) Ruby-like numerical loops with a times method, and 3) simple utility methods like toColorPart. Examples are given for each method, such as using succ to return the successor of a number, times to iterate a callback 0 to n times, and toColorPart to generate a 2-digit hex color code from a number.
