HP calculators sometimes define 

lnp1(x)  = ln(1 + x) 
expm1(x) = exp(x) - 1 

to deal accurately and quickly with the special case where x<<1. This may not be
useful in an environment of pseudo-infinite precision, unless speed begins to
matter alot. Maybe they could be called automagically when the compiler sees
something like the RHS of the above as an optimization.
