fmax, fmaxf, fmaxl, fmin, fminf, fminl -- floating-point maximum and min-
Math Library (libm, -lm)
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);
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
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.

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 NetBSD 5.1.
