MAX(3) Linux Programmer's Manual MAX(3)
MAX, MIN - maximum or minimum of two values
#include <sys/param.h>
MAX(a, b);
MIN(a, b);
These macros return the maximum or minimum of a and b.
These macros return the value of one of their arguments, possibly
converted to a different type (see BUGS).
These macros may raise the "invalid" floating-point exception
when any of the arguments is NaN.
These nonstandard macros are present in glibc and the BSDs.
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.
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.
#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);
}
fmax(3), fmin(3)
