Subject: catacomb/__init__.py (BaseRat, MP, GF): Add missing true-division methods.
X-Git-Url: https://git.distorted.org.uk/~mdw/catacomb-python/commitdiff_plain/b47818ea1ee2c0755249b9ca940083b6dd73acb3?ds=sidebyside

catacomb/__init__.py (BaseRat, MP, GF): Add missing true-division methods.

Since these all produce exact (rational) results, they satisfy the true-
division requirements.
