Dear freshmeat.net subscriber,

witharr just announced version 1.5.7 of GiNaC on freshmeat.net.

The changes are as follows:

This release fixes a bug in the GCD code (an infinite loop in pgcd())
and a bug in atan2() (a division by zero error for atan2(x,0) if
x is a negative and composite term). Products now correctly set
info_flags::negative and info_flags::negint.

Project description:

GiNaC (GiNaC is Not a CAS (Computer Algebra System)) is a C++ library for
symbolic calculations. It is designed to allow the creation of integrated
systems that embed symbolic manipulations together with more established areas
of computer science (like computation-intense numeric applications, graphical
interfaces, etc.). Contrary to other CASes it does not try to provide 
extensive
algebraic capabilities and a simple programming language but instead accepts a
given language (C++) and extends it by a set of algebraic capabilities.
