I object to its characterization as "nicer". It's faster, but *lower 
precision*. It worries me that people are so blithely abandoning those extra 
bits in the name of speed. A few years from now there's going to be an 
expensive engineering failure, and months of investigation will reveal that 
it was because a math library was compiled for SSE2. Be careful out there.

(And while I'm on the subject, Haskell should have a LongDouble type.)
