libRational provides a C++ class interface around the rational numbers (mpq_t) of GNU MP. It adds special value support and a mechanism to reduce useless copying of temporary objects.

There was a serious bug in the 'non-specialvalue'
version, in which comparison of a rational to 0
often returned an incorrect result. Furthermore, a
self-assignment problem for the BigInt division
has been fixed, and support for SpecialValue 0.4.0
has been added.
The integrated SpecialValue library has been
removed, so the user is now required to download
and install SpecialValue before installing
libRational. The new installer script can be used
to automate this process. This version cooperates
with the new interface of SpecialValue-0.3.0.
This new version compiles under Linux, Solaris, and FreeBSD. SpecialValue no longer needs to be downloaded separately, and dynamic library building is supported. The code is being reorganized in order to facilitate a --disable-specialvalue configure option.
