FMAX(3) Library Functions Manual FMAX(3)NAMEfmax,fmaxf,fmaxl,fmin,fminf,fminl- floating-point maximum and minimum functionsLIBRARYMath Library (libm, -lm)SYNOPSIS#include<math.h>doublefmax(double x, double y); floatfmaxf(float x, float y); long doublefmaxl(long double x, long double y); doublefmin(double x, double y); floatfminf(float x, float y); long doublefminl(long double x, long double y);DESCRIPTIONThefmax(),fmaxf(), andfmaxl() functions return the larger of x and y, and likewise, thefmin(),fminf(), andfminl() functions return the smaller of x and y. They treat +0.0 as being larger than -0.0. If one argument is an NaN, then the other argument is returned. If both arguments are NaNs, then the result is an NaN. These routines do not raise any floating-point exceptions.SEEALSOfabs(3), fdim(3), math(3)STANDARDSThefmax(),fmaxf(),fmaxl(),fmin(),fminf(), andfminl() functions conform to ISO/IEC 9899:1999 ("ISO C99").HISTORYThese routines first appeared in FreeBSD 5.3 and NetBSD 5.1.
