yeah - it's a *huge* number space :)

but... it's impossible to dither correctly in FP, so, each time you multiply, 
you're effectively doubling the quantisation distortion. Keep in mind also, that 
your mantissa is only 24 bits.

This is maybe okay if your signal only goes through a few multiplies from the 
input of your app to the output. but, suppose you're running logic. count the 
multiplies in your signal chain.

so you go to double precision ;)
