Sh NAME
Nm fmax ,
Nm fmaxf ,
Nm fmaxl ,
Nm fmin ,
Nm fminf ,
Nm fminl
Nd floating-point maximum and minimum functions
Sh LIBRARY
Lb libm
Sh SYNOPSIS
In math.h
Ft double
Fn fmax "double x" "double y"
Ft float
Fn fmaxf "float x" "float y"
Ft "long double"
Fn fmaxl "long double x" "long double y"
Ft double
Fn fmin "double x" "double y"
Ft float
Fn fminf "float x" "float y"
Ft "long double"
Fn fminl "long double x" "long double y"
Sh DESCRIPTION
The
Fn fmax ,
Fn fmaxf ,
and
Fn fmaxl
functions return the larger of
Fa x
and
Fa y ,
and likewise, the
Fn fmin ,
Fn fminf ,
and
Fn fminl
functions return the smaller of
Fa x
and
Fa y .
They treat
Li +0.0
as being larger than
Li -0.0 .
If one argument is an \*(Na, then the other argument is returned.
If both arguments are \*(Nas, then the result is an \*(Na.
These routines do not raise any floating-point exceptions.

Sh STANDARDS
The
Fn fmax ,
Fn fmaxf ,
Fn fmaxl ,
Fn fmin ,
Fn fminf ,
and
Fn fminl
functions conform to
St -isoC-99 .
Sh HISTORY
These routines first appeared in
Fx 5.3
and
Nx 5.1 .
