No comment on this one?  I don't know which compilers are
available for it, but it does seem to still be in production.

Why is it off topic?  Fortran allows any base greater than one.
PL/I definitely allows decimal, most likely even for FIXED
BINARY variables.  Someone else will have to say what ADA allows,
but those three groups are in the discussion, so those should
determine what is on topic.
