+.TH MAX 3 (date) "Linux man-pages (unreleased)"
+.SH NAME
+MAX, MIN \- maximum or minimum of two values
+.SH LIBRARY
+Standard C library
+.RI ( libc ", " \-lc )
+.SH SYNOPSIS
+.nf
+.B #include <sys/param.h>
+.P
+.BI MAX( a ", " b );
+.BI MIN( a ", " b );
+.fi
+.SH DESCRIPTION
+These macros return the maximum or minimum of
+.I a
+and
+.IR b .
+.SH RETURN VALUE
+These macros return the value of one of their arguments,
+possibly converted to a different type (see BUGS).
+.SH ERRORS
+These macros may raise the "invalid" floating-point exception
+when any of the arguments is NaN.
+.SH STANDARDS
+GNU, BSD.
+.SH NOTES
+If either of the arguments is of a floating-point type,
+you might prefer to use
+.BR fmax (3)
+or
+.BR fmin (3),
+which can handle NaN.
+.P
+The arguments may be evaluated more than once, or not at all.
+.P
+Some UNIX systems might provide these macros in a different header,
+or not at all.
+.SH BUGS
+Due to the usual arithmetic conversions,
+the result of these macros may be very different from either of the arguments.
+To avoid this, ensure that both arguments have the same type.
+.SH EXAMPLES
