There is no evidence that the regular Number.toString() method is broken.  I'm attaching two test cases, one in Scheme and one in ActionScript, that print floating-point numbers of known representation.  The Scheme code was run on an implementation that is assumed to be correct, because its implementors care[1].  The ActionScript output is identical, except for the case 1.0 where the rules for AS are different anyway.

So it seems that we have problems with the formatting functions toFixed, toPrecision, and toExponential, because these have certain strange rules that our number printer can't handle yet.  And it seems like we have problems with number parsing because we're using a naive algorithm.
