Printing Float

[Waldek Hebisch]

I would like to separate blocks of digits in Float using underscores
(as opposed to blanks). That is `exp(2.0)' would give:

7.3890560989_306502272

instead of

7.3890560989 306502272

The main reason is to make FriCAS output closer to its input,
but also I think that with undercores is is clearer that
what is printed is a single number and not several.

I would prefer just to change separator character, but if
somebody really like or depend on blanks we could make
the separator settable.

Opinions?

Underscore is OK and also preferable, because it allows paste output as
input.

I've no clear opinion on this. In fact, for me it would also be OK to
replaces " " by "", i.e. remove the space completely.

That is actually settable now, see 'outputSpacing' in Float
(with parameter 0 it supresses separator).
