That is good to hear.

As a minor documentation issue, because there will be people exposed to
C or Java who expect functions called round, trunc, floor, ceil to be
in the same place as sqrt and acosh, it would be helpful if the
manual page for the math module mentioned these functions, maybe at the
end, and said where to really find them.  I'm not talking about
repeating their descriptions, just pointing to them.
