Osman> Version 5.5 using gcl gets it correct:
That's because in gcl all floats are double-floats, unlike cmucl and
clisp. I'm pretty sure the code that handles this is doing (float x)
when it should have done (float x 1d0). It's confusing that maxima
also has a float macro, and I can never tell if it's the maxima macro
or the Lisp function that's being called.
I'm too lazy to look at it right now, but will eventually.
