FMAX(3) BSD Programmer's Manual FMAX(3)
fmax, fmaxf, fmaxl, fmin, fminf, fminl - floating-point maximum and
minimum functions

fmax(double x, double y);

fmaxf(float x, float y);

fmaxl(long double x, long double y);

fmin(double x, double y);

fminf(float x, float y);
long double
fminl(long double x, long double y);
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 ar-
gument 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.
fabs(3), fdim(3), math(3)
The fmax(), fmaxf(), fmaxl(), fmin(), fminf(), and fminl() functions con-
form to ISO/IEC 9899:1999 ("ISO C99").
These routines first appeared in FreeBSD 5.3 and .
