fmax(3M) Mathematical Library Functions fmax(3M)NAME

fmax, fmaxf, fmaxl - determine maximum numeric value of two floating-point numbersSYNOPSIS

c99 [ flag... ] file...[ library... ] #include <math.h> double fmax(double x, double y); float fmaxf(float x, float y); long double fmaxl(long double x, long double y);-lmDESCRIPTION

These functions 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, these functions choose the numeric value.RETURN VALUES

Upon successful completion, these functions return the maximum numeric value of their arguments. If just one argument is a NaN, the other argument is returned. If x and y are NaN, a NaN is returned.ERRORS

No errors are defined.ATTRIBUTES
