Replaced usages of Math::floorFloat() with (int) floor() and Math::ceilFloat() with (int) ceil()

Browse Source 
Once upon a time, these userland functions were faster than calling builtins, but not anymore. According to my test the Math functions are twice slower in PHP 7.2 with typehints and 50% slower without typehints.

Inlining is slightly faster than using builtins, but the difference is very small - not worth making the code look any more ugly than it does already.
