ok this is kinda hard to explain

i have two values 64 and 128 respectively
now my program will only ever see one at a time but in a formula i have displaying a sprite, it takes into account the size of the bitmap (which is either 64 or 128)

i need to add into the formula a sub-formula which will use the variable(128 or 64) and return a 2 if it is 128 and a 4 if it is 64.

i dont want to use ifs or selects because it is in a "high-traffic" function of my program.

i was wondering if there was a way to manipulate those 2 numbers so that it will become 4 for 64 and 2 for 128.

thanks guys

What you need is:

ans = 6 - (n/32)

where n is either 64 or 128

No, not stupid at all, everyone often misses the simpliest of things that can stare us in the face for hours
