a personnal view here. i'm always perplex when there
are many magic numbers in some code. unless i know how
to compute these numbers.

however, as with the cephes library, no doubt that the
code will be much more robust, efficient and accurate.
but also much more difficult to implement, hundred lines
of code instead of a few lines.
