Boost might be a good place to look for implementation
ideas.  Looking at the msun code also works.  As does
searching with google.  This is all secondary to the 
real issue.  The real problem is no one is willing to
step forward to actually help write and test the code.
Everyone seems to be waiting (and complaining!) for
someone else to do the work.  I've been chipping away at
libm issues since 2003, and given my available free time
I should have a fully compliant C99 libm around 2025 or
so.
