Ideas for rewrite of libm-test

[Andreas Jaeger]

I've looked in more details in the rewrite of libm-test and have one
more question:

     How should we define the error tolerances?

Currently libm-test uses absolute errors (the difference between a
precalculated value and the calculated value).

But if we want to describe the overall error of a function, we should
use relative errors like 2^-63.  

Should we also specify intervals with their errors?

Btw. I'd like to read a little bit more about this topic.  I've read
already a number of articles from the different ACM journals but if
anybody has more pointers to relevant literature, please tell me.
