Subject: mostly fixed in FriCAS
Message-ID: <20071228163723-0800@axiom-wiki.newsynthesis.org>

Status: open => fix proposed 

it remains to teach axiom algorithms for Gamma & friends with 'Float' (not 'DoubleFloat') arguments, and that 'Complex DoubleFloat has SpecialFunctionCategory'.

The latter seems to be a bit tricky, unless we do it by special case in 'Complex', which is ugly.
