I'd like to ask if it's possible to add expm1 and log1p to
the Floating class:
class ... Floating a where
...
exp, log, sqrt :: a -> a
expm1, lop1p :: a -> a -- new, copied from C99
...
expm1 x = exp x - 1 -- but done more accurately
log1p x = log (1 + x) -- but done more accurately
However, the Library_submissions page wants an implementation, and
adding this sort of function seems to require getting into the guts
of an implementation. (Difficult: I am having serious trouble getting
GHC 6.6 to install at all, never mind changing it.)
