Because the optimisation page on the haskell wiki is very explicit
about never using Float when you can use Double, that's why.

Is that still true if you use -fexcess-precision ?
Why on earth would you use -fexcess-precision if you're using Floats?
The excess precision only apples to Doubles held in registers on x86
IIRC. (If you spill a Double from a register to memory, then you lose
the extra precision bits in the process).
Unless -fexcess-precision with ghc does something completely different
to the analogous gcc setting that is.
