Gcalctool is the default GNOME desktop calculator.

It has Basic, Advanced, Financial and Scientific modes. Internally it uses multiple precision arithmetic to produce results to a high degree of accuracy.

This release is for GNOME 2.13.5. I did release a tarball (5.7.23) last Friday for the 2.13.5 GNOME distribution, but since then, two important gcalctool bugs have been found and hopefully fixed, so if it's not too late, I'd like this tarball to be considered instead.
