31.Sh NAME
32.Nm fmax ,
33.Nm fmaxf ,
34.Nm fmin ,
35.Nm fminf
36.Nd floating-point maximum and minimum functions
37.Sh LIBRARY
38.Lb libm
39.Sh SYNOPSIS
40.In math.h
41.Ft double
42.Fn fmax "double x" "double y"
43.Ft float
44.Fn fmaxf "float x" "float y"
45.Ft double
46.Fn fmin "double x" "double y"
47.Ft float
48.Fn fminf "float x" "float y"
49.Sh DESCRIPTION
50The
51.Fn fmax
52and
53.Fn fmaxf
54functions return the larger of
55.Fa x
56and
57.Fa y ,
58and likewise, the
59.Fn fmin
60and
61.Fn fminf
62functions return the smaller of
63.Fa x
64and
65.Fa y .
66They treat
67.Li +0.0
68as being larger than
69.Li -0.0 .
70If one argument is an \*(Na, then the other argument is returned.
71If both arguments are \*(Nas, then the result is an \*(Na.
72These routines do not raise any floating-point exceptions.
73.Sh SEE ALSO

77.Sh STANDARDS
78The
79.Fn fmax ,
80.Fn fmaxf ,
81.Fn fmin
82and
83.Fn fminf
84functions conform to
85.St -isoC-99 .
86.Sh HISTORY
87These routines first appeared in
88.Fx 5.3
89and
