It's easy to implement with the code you've provided.
No need for yet another one rarely used core function.

Description:
------------
not really a bug, but i'd like to suggest a new math-function sgn().
it would make comparison of integer values much easier (an nicer, of
course ;)).
i've attached an example in the srccode part.
Reproduce code:
---------------
<?php
// comparison with if/else :
if($a < $b) print("a < b");
elseif($a == $b) print("a == b");
else print("a > b");
// comparison with sgn() :
function sgn($int) {
if($int > 0) return 1;
if($int < 0) return -1;
return 0;
}
switch(sgn($a-$b)){
case 1: print("a > b");
case 0: print("a == b");
case -1: print("a < b");
}
?>
Expected result:
----------------
depends ;)
Actual result:
--------------
depends ...
