This library contains examples of how mathematical routines might be
implemented in C. It is in two parts
dcl.c which is a complete double
precision maths library and
ccl.c which is the complex number equivalent.
Also included are the include file
the error descriptions
and the constants used
These libraries were originally written in the "good ol'days" when most C
development platforms did not have good double precision maths routines
and certainly didn't have complex number support.
Now they can be used to illustrate the techniques and mathematics
(especially for the complex library) behind the functions we take for granted.
