NAME

       MAX, MIN - maximum or minimum of two values

SYNOPSIS

       #include <sys/param.h>

       MAX(a, b);
       MIN(a, b);

DESCRIPTION

       These macros return the maximum or minimum of a and b.

RETURN VALUE

       These macros return the value of one of their arguments, possibly converted to a different
       type (see BUGS).

ERRORS

       These macros may raise the "invalid" floating-point exception when any of the arguments is
       NaN.

CONFORMING TO

       These nonstandard macros are present in glibc and the BSDs.

NOTES

       If either of the arguments is of a floating-point type, you might prefer to use fmax(3) or
       fmin(3), which can handle NaN.

       The arguments may be evaluated more than once, or not at all.

       Some UNIX systems might provide these macros in a different header, or not at all.

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.

EXAMPLES

       #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>\n", argv[0]);
               exit(EXIT_FAILURE);
           }

           a = atoi(argv[1]);
           b = atoi(argv[2]);
           x = MAX(a, b);
           printf("MAX(%d, %d) is %d\n", a, b, x);

           exit(EXIT_SUCCESS);
       }
