This is why I prefer to use fixed decimal. In your own private code, 
it's easy enough to implement. You just decide how many "decimals" your 
int's should have.

Getting correct programs using floats are really hard. Heck, MS Excell 
don't even get Sum and Mean right. (Microsoft, usually, use na誰ve 
algorithm's that don't take care of underflow and rounding errors).
