For this type of work however I'd argue the math hasn't.  They're using
easy to implement simple equations to convert to code and the given
coefficients will produce values within the ranges they've provided.  I'd
still consider it a good reference for that. (Got another 2 volume more
comprehensive set Basic Scientific Subroutines)

Lots of old computer books focus more on the algorithms and techniques than
newer list the library and here's some examples.
