\| \| \| \| \| \| \| \| \| \| \|	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.
