+.Sh NAME
+.Nm fmaximum_mag ,
+.Nm fmaximum_magf ,
+.Nm fmaximum_magl ,
+.Nm fminimum_mag ,
+.Nm fminimum_magf ,
+.Nm fminimum_magl
+.Nd floating-point maximum and minimum magnitude functions
+.Sh LIBRARY
+.Lb libm
+.Sh SYNOPSIS
+.In math.h
+.Ft double
+.Fn fmaximum_mag "double x" "double y"
+.Ft float
+.Fn fmaximum_magf "float x" "float y"
+.Ft "long double"
+.Fn fmaximum_magl "long double x" "long double y"
+.Ft double
+.Fn fminimum_mag "double x" "double y"
+.Ft float
+.Fn fminimum_magf "float x" "float y"
+.Ft "long double"
+.Fn fminimum_magl "long double x" "long double y"
+.Sh DESCRIPTION
+The
+.Fn fmaximum_mag ,
+.Fn fmaximum_magf ,
+and
+.Fn fmaximum_magl
+functions determine the larger of the absolute values of
+.Fa x
+and
+.Fa y ,
+and return the argument with the larger absolute value.
+If the absolute values are equal, the behavior is equivalent to calling the corresponding
+.Fn fmaximum
+function on the arguments.
+.Pp
+Likewise, the
+.Fn fminimum_mag ,
+.Fn fminimum_magf ,
+and
+.Fn fminimum_magl
+functions determine the smaller of the absolute values of
+.Fa x
+and
+.Fa y ,
+and return the argument with the smaller absolute value.
+If the absolute values are equal, the behavior is equivalent to calling the corresponding
+.Fn fminimum
+function on the arguments.
+.Pp
+If either argument is an \*(Na, then the result is an \*(Na.
+These routines do not raise any floating-point exceptions.

+.Sh STANDARDS
+The
+.Fn fmaximum_mag ,
+.Fn fmaximum_magf ,
+.Fn fmaximum_magl ,
+.Fn fminimum_mag ,

+functions conform to
