C mathematical functions
C standard library header file providing mathematical functions / From Wikipedia, the free encyclopedia
C mathematical operations are a group of functions in the standard library of the C programming language implementing basic mathematical functions.[1][2] All functions use floating-point numbers in one manner or another. Different C standards provide different, albeit backwards-compatible, sets of functions. Most of these functions are also available in the C++ standard library, though in different headers (the C headers are included as well, but only as a deprecated compatibility feature).
