I just use my ears instead of calculation. 
The increase in body, depth, definition is massive, when comparing an 
identical multitrack session between Logic Pro and Cubase (6). 
Regardless of floating point whatever. Just try it out. Its the only test 
that works when in danger of getting lost in technical data comparison 
without the ability to verify in detail, what manufacturers tell you to 
sell their software. Called ears.
