Subject: Elementary Function Test Routines in C

Does anyone know of any routines (preferably public-domain or at least
freely usable) written in C for testing the elementary functions
(sin, cos, tan, exp, ln, exponentation, etc.)? I am aware of a group
of routines written in Fortran available from
If worst comes to worst, I could convert these to C, but if someone
out there has already done the work . . .

[Ed. Note: The Cody and Waite test suite, known as ELEFUNT, is written
in Fortran and available from Netlib. Chris Jensen at the University
of New Mexico translated part, if not all, of ELEFUNT to C several
years ago. I may be able to find her work on an old backup tape if nobody
has anything more accessible. --Cleve ]

Subject: Complex Arithmetic in C

I am about to translate a large FORTRAN program to C. The one problem
which bugs me most is the lack of complex arithmetic in C, as the
program I am working on requires a lot of complex arithmetic. Does anyone
have or know of a library of functions or macro's, which will implement
complex arithmetic - or do I have to translate all the complex operations
to real ?.
