float % int could lead to rounding difficulties, which is not a bug.

Integer limited to 2047000000 so there.

Appears to be broken on large(r) integers. Is this a limitation on the type used? (I am coding
working ip2long/long2ip).
$temp = 3194548456;
print "correct: " . ($temp - 255*floor($temp/255));
print "php: " . $temp % 255 . "<br>";
as defined in maths, the % is equiv to MOD(n, d) = n - d*INT(n/d)
where n is the number, d is the divisor.
