Comment on attachment 359866 [details] Patch r=me. Is there already a test that verifies that -0 compares work correctly? I think there probably is, but if you not, can you add one?

Hi, thanks for the review! I've thought about writing tests, but there seemed to be enough tests: JSTests/stress/math-(floor|trunc|round|ceil)-basics.js, JSTests/stress/op_div_<something> and JSTests/stress/arith-(round|floor|ceil|trunc)-on-various-types.js.
