Math.h

Math.h

math.h is a header file in the standard library of C programming language designed for basic mathematical operations. Most of the functions involve the use of floating point numbers. C++ also implements these functions for compatibility reasons and declares them in the header cmath.

All functions that take or return an angle work in radians.

All these functions take doubles for floating-point arguments, unless otherwise specified. To work with floats or long doubles, append an f or an l to the name, respectively.

Pre-C99 functions

The double-to-string conversion functions ecvt, fcvt and gcvt have been deprecated in favour of sprintf.
