In the Numeric Types documentation for 2.6, 3.0, and 3.1 trunc is
documented as a built-in, like round, but while there is a trunc in math
there is no built-in trunc. Read some of the debate on trunc from a year
ago convinced me that this discrepancy is a documentation problem not a
problem with the built-in functions. Sorry if I'm completely off target
here, but since I noticed I figured it was worth an issue.

Confirmed for 3.0 that trunc does not exist in the builtins module and
is not listed in the Built-in functions section but is listed in the
Numeric Types section. So I agree "trunc(x) x truncated to Integral "
should leave the Operation table.
Yes, MM, we do want to clean up such discrepancies.
trunc is in the math module and is listed in its doc.

Thanks, fixed in r68721.
