When binary operations are required it's usually for speed issues, and to 
have to round it each time in a specific way is just a nightmare on x86 
(massive overhead)... and given that a fractional number being passed to a 
bit function is a case of "Garbage In", garbage out seems perfectly fine to 
me.

Be interested to see what Mike Pall has to say though ;), but as a user I 
can say predictable rounding of fractional numbers is not on my list of 
priorities at all - we're given math.floor, math.ceil if we ever need to 
write a wrapper around the bit library.
