You ought to have a look at the book "Software Manual for the Elementary
Functions" by Cody and Waite.  It describes how to implement these functions,
but also gives extensive test programs.  It contains a few errors, on the
other hand the descriptions are very clear and it describes a number of
pitfalls both in design as well as in testing.  It is however based on Fortran.
