Programming operations, using maths

An important part of computer programming is implementing mathematic operations. Maths can be used to implement many functions in an application; be it to include functionality that is obviously maths related, or to implement functions that may not immediately appear, to the user, as a maths problem; such as calculating the window size to maintain the correct aspect ratio, or to calculate the width of a field that is to be half the width of the window.

Code comments offer a method of annotation for the code that makes up an application, a part of an application, or simply a single line of code. When source code is compiled, or executed comments are ignored; they have no affect on the final product, the output of a method, or what a line of code produces.
