I see what you mean, the ccalc help does not quite match the results.

This is also confusing because we are talking about options to the
ccalc program (e.g. -int, -fint), not mathematical expressions which
are the foundation of ccalc and 3dcalc (e.g. int() and floor(), if
floor were actually implemented, which it is not :).

So either the help or the computations should probably be modified,
depending on what is intended for those options (which we should not
presume).

It might be even more useful and appropriate to get floor() and ceil()
implemented as ccalc/3dcalc expressions.

More on this Tuesday, probably.
