smaller float

[nobody_]

I'm sorry, I'm not sure whether I get your reply :)
Is what you propose different than doing:

short s=0;

s++100; //s++1.00
s*3

x=x+(s/100.0); // divide it when it is used

My way is not really nice as you need to divide it every time you use it.
How would, what you propose, work?
(sorry about not getting your post :(
