C mathematical functions

Last update on December 24 2022 12:44:54 (UTC/GMT +8 hours)

C mathematical operations are a group of functions in the standard library of the C programming language implementing basic mathematical functions. All functions use floating-point numbers in one manner or another. Different C standards provide different, albeit backwards-compatible, sets of functions.

The <math.h> include file declares the math manipulation functions:
