At some point in the dim mists of prehistory, somebody thought it would
be cute to define prefix % as trunc() and postfix % as round(). I'm not
aware of any precedent for that; it was probably mostly an exercise in
testing out the grammar.
Now that I look, it doesn't look like these operators are documented
at all in the SGML docs, so it sure seems that removing them should be
pretty painless.
