I believe the main reason of using floating points in move valuation in
GNU Go is the readability.  It's natural to value a move to 1.5 points
instead of say 0x18000.  Since this is no way a time-critical piece of
code, readability is one of the most important aspects here.

Absolutely.

Yes.  Versions of GNU Go play slower and slower, but only a little.  Current
GNU Go would play much slower than it does if we didn't do all the speed
optimizations.
