Very nice?thanks for the link.
David: I must have overlooked round,truncate,ceiling. I think I didn't realize
that they
don't return the same type that they take as argument. Anyway, "round" worked.
Thanks!

Ok, I see, if you have to modify such an internal function, then
forking the package might really be the only solution.
If you're using a cabal sandbox with 'add-source', then you
might not need to rename the gloss package, if cabal first searches
for dependencies in the added sources and then on hackage. But
I'm not sure about this one.
Greetings,
Daniel

Yes, that's what it does. Renaming the package should not be
necessary.
