I don't have an answer to your ANTLR problem, but I'm curious why
you want to make that particular change. If you're trying to make
it do rounding instead of truncation, then a better alternative
would be to convert any "Math.floor(x)" into "int(x+0.5)"
(although that'll only work right when x is positive). Both are
still semantically different from what Math.floor does normally...
