NAME

       MAX, MIN - maximum or minimum of two values

LIBRARY

       Standard C library (libc, -lc)

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.

STANDARDS

       GNU, BSD.

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);
       }
