In my own software, and for example in my games, speed is often 
paramount. I got some spectacular improvements on overall performance by 
liberaly using #asFloat. I even implemented #/// as follow:

Number /// aNumber

	^ self / aNumber asFloat

for cases (which I found many) where I want to ensure that a division 
will never return a Fraction.
