FMAX(3)                 NetBSD Library Functions Manual                FMAX(3)


NAME

     fmax, fmaxf, fmaxl, fmin, fminf, fminl -- floating-point maximum and min-
     imum 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 argu-
     ments 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 con-
     form to ISO/IEC 9899:1999 (``ISO C99'').
