## Re:fixed point math

Fixed Point Math is when you need to speed up your

math calculations in something that doesn't need

lots of accuracy - i.e. 3d Games, Simulations - most

3d stuff.

So, instead of making a cube that's 1 unit in size and

using real or double or extended and getting fractions when

you rotate it, you use, say 100 and use DIV instead of /

to speed up the calculations.

What happens is that accuracy is reduced and your object

"wobbles" a bit but you speed up calculation. As for

separating the bits to make it a decimal, I think that that's

what the computer would do anyway if you used Floating

Point Math. Not much point there.
