Hello, im trying to speed up my game a bit by reducing the number of clips on stage at a particular interval…however i dont want to just hack at the clips, instead i was gonna reduce the clips but maintain the same ratio.

ie 28:67:90

as you can see this presents preblem because first i have to determine a common denominator. Anyway, what i want to do is round the numbers up to the nearest even number and then divide by 2.

I have no idea how to round up to the nearest even number tho?? any ideas?
