+.Sh NAME
+.Nm fmaximum ,
+.Nm fmaximumf ,
+.Nm fmaximuml ,
+.Nm fminimum ,
+.Nm fminimumf ,
+.Nm fminimuml
+.Nd floating-point maximum and minimum functions
+.Sh LIBRARY
+.Lb libm
+.Sh SYNOPSIS
+.In math.h
+.Ft double
+.Fn fmaximum "double x" "double y"
+.Ft float
+.Fn fmaximumf "float x" "float y"
+.Ft "long double"
+.Fn fmaximuml "long double x" "long double y"
+.Ft double
+.Fn fminimum "double x" "double y"
+.Ft float
+.Fn fminimumf "float x" "float y"
+.Ft "long double"
+.Fn fminimuml "long double x" "long double y"
+.Sh DESCRIPTION
+The
+.Fn fmaximum ,
+.Fn fmaximumf ,
+and
+.Fn fmaximuml
+functions return the larger of
+.Fa x
+and
+.Fa y ,
+and likewise, the
+.Fn fminimum ,
+.Fn fminimumf ,
+and
+.Fn fminimuml
+functions return the smaller of
+.Fa x
+and
+.Fa y .
+They treat
+.Li +0.0
+as being larger than
+.Li -0.0 .
+.Pp
+Unlike the
+.Xr fmax 3
+family of functions, which ignore an \*(Na, if either argument to
+.Fn fmaximum
+or
+.Fn fminimum
+is an \*(Na, then the result is an \*(Na.
+These routines do not raise any floating-point exceptions.
+.Sh SEE ALSO
+.Xr fmax 3 ,
+.Xr fmaximum_num 3 ,
+.Xr fmaximum_mag 3 ,
+.Xr math 3
+.Sh STANDARDS
+The
+.Fn fmaximum ,
+.Fn fmaximumf ,
+.Fn fmaximuml ,
+.Fn fminimum ,
+.Fn fminimumf ,
+and
+.Fn fminimuml
+functions conform to
+.St -isoC-2023 .
+.Sh HISTORY
+These routines first appeared in
+.Fx 16.0 .
