Why are integers used in computer programming? Integers are a simple and efficient way to represent whole numbers in computer programming. They can be used for a wide range of tasks, from simple calculations to complex algorithms. They are also easy to understand and manipulate, making them a ...
Computer algorithms are used to compute many things. This site looks at some of the algorithms used in mathematical computations. Looking first at large integers (those numbers that exceed the computer's intrinsic byte or word size), we examine what is involved in providing addition and ...

(After publishing this I realized that the C statements above are processed by the compiler — constant folding. There’s no guarantee that the compiler will use floating-point division and multiplication instructions; it could use its own algorithms. My point is still valid though. In a real ...
