Alright, it makes sense, thanks.

I just didn't expect the test to be that strict.
For instance, math.integer(600eX/5eX) returns 120 for X going from -5 to 
20 (didn't test beyond that), and nil below -5.

how to reply properly, hopefully I don't break anything, sorry if I do =/

PPS: Lua is a great lib.
