math.h

This category includes the floating-point mathematical functions of the C
run-time library. The mathematical functions are ANSI standard. The
header file contains prototypes for functions used to calculate

mathematical properties of single-precision floating type variables. On the

data type.
The file also defines the macro

Some of the functions in this header file exist as both integer and floating
point. The floating-point functions typically have an
