clamp

Ensures that x is between the limits set by low and high. If low is greater than high the result is undefined.

For example:

 CLAMP(5, 10, 15) is 10.
 CLAMP(15, 5, 10) is 10.
 CLAMP(20, 15, 25) is 20.

Example: Clamp:

public static int main (string[] args) {
	// Output: ``j``
	unichar c = ((unichar) 'e').clamp ('j', 'o');
	print ("%s\n", c.to_string ());

	// Output: ``j``
	c = ((unichar) 'o').clamp ('e', 'j');
	print ("%s\n", c.to_string ());

	// Output: ``t``
	c = ((unichar) 't').clamp ('o', 'y');
	print ("%s\n", c.to_string ());

	return 0;
}
