Version 28 attached has double variables, although typing is based on
guessing because it is just a string.

Any comment?

The two features are highly intermix, so it can only be dependent patches,
first to add a function infrastructure and probably some support for
doubles altough it would not be used, then to add doubles & their

A real pain is the documentation, because it means writing a documentation
with only integer functions, then overwriting it with doubles. This is
dumb work, really, for the sake of "a cleaner git history", the beauty of
it no one will ever contemplate...
