Determines the maximum numeric value of two floating-point numbers.
#include <math.h> double fmax (x, y) double x; double y; float fmaxf (x, y) float x; float y; long double fmaxl (x, y) long double x; long double y;
The fmax, fmaxf, and fmaxl subroutines determine the maximum numeric value of their arguments. NaN arguments are treated as missing data. If one argument is a NaN and the other numeric, the fmax, fmaxf, and fmaxl subroutines choose the numeric value.
| x | Specifies the value to be computed. |
| y | Specifies the value to be computed. |
Upon successful completion, the fmax, fmaxf, and fmaxl subroutines return the maximum numeric value of their arguments.
If one argument is a NaN, the other argument is returned.
If x and y are NaN, a NaN is returned.
