+.SH NAME
+MAX, MIN \- maximum or minimum of two values
+.SH SYNOPSIS
+.nf
+.B #include <sys/param.h>
+.PP
+.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 CONFORMING TO
+These nonstandard macros are present in glibc and the BSDs.
+.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.
+.PP
+The arguments may be evaluated more than once, or not at all.
+.PP
+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
+.EX
+#include <stdio.h>
+#include <stdlib.h>
+#include <sys/param.h>
+
+int
+main(int argc, char *argv[])
+{
+ int a, b, x;
+
+ if (argc != 3) {
+ fprintf(stderr, "Usage: %s <num> <num>\en", argv[0]);
+ exit(EXIT_FAILURE);
+ }
+
+ a = atoi(argv[1]);
+ b = atoi(argv[2]);
+ x = MAX(a, b);
+ printf("MAX(%d, %d) is %d\en", a, b, x);
+
+ exit(EXIT_SUCCESS);
+}
