-.TH MAX 3 2023-10-31 "Linux man-pages 6.7"
-.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
-.\" SRC BEGIN (MAX.c)
-.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);
