Subject: [ANN] Intervals: Interval arithmetic in Ruby

Intervals is a library implementing an interval system in the extended
real set that is closed under arithmetic operations. Correct rounding
ensures that the operations are inclusion-wise monotonic.

Intervals pre-1 is an experimental release that has has been tested on
Mac Os X/powerpc and on linux/intel. For the C package implementing
rounding-mode control to compile, a C99-compliant compiler is needed
(or at least one that knows about fenv.h).

The project homepage is at http://intervals.rubyforge.org/ and the
library can be downloaded from http://rubyforge.org/projects/intervals/

Feedback and suggestions are welcome!

Best regards,
Stefano Taschini
