H A Dk_exp.c226597 Fri Oct 21 06:35:50 MDT 2011 das The cexp() and {,c}{cos,sin}h functions all need to be able to compute
exp(x) scaled down by some factor, and the challenge is doing this
accurately when exp(x) would overflow. This change replaces all of
the tricks we've been using with common __ldexp_exp() and
__ldexp_cexp() routines that handle all the scaling.

bde plans to improve on this further by moving the guts of exp() into
k_exp.c and handling the scaling in a more direct manner. But the
current approach is simple and adequate for now.
