FMAX(3)                    Library Functions Manual                    FMAX(3)

NAME
     fmax, fmaxf, fmaxl, fmin, fminf, fminl - floating-point maximum and
     minimum functions

LIBRARY
     Math Library (libm, -lm)

SYNOPSIS
     #include <math.h>

     double
     fmax(double x, double y);

     float
     fmaxf(float x, float y);

     long double
     fmaxl(long double x, long double y);

     double
     fmin(double x, double y);

     float
     fminf(float x, float y);

     long double
     fminl(long double x, long double y);

DESCRIPTION
     The fmax(), fmaxf(), and fmaxl() functions return the larger of x and y,
     and likewise, the fmin(), fminf(), and fminl() 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.

SEE ALSO
     fabs(3), fdim(3), math(3)

STANDARDS
     The fmax(), fmaxf(), fmaxl(), fmin(), fminf(), and fminl() functions
     conform to ISO/IEC 9899:1999 ("ISO C99").

HISTORY
     These routines first appeared in FreeBSD 5.3 and NetBSD 5.1.
