           Summary: Acid3 reveals broken behavior in toFixed and
                    toExponential
           Product: WebKit
           Version: 525+ (Nightly build)
          Platform: Macintosh
        OS/Version: Mac OS X 10.4
            Status: NEW
          Keywords: EasyFix
          Severity: Normal
          Priority: P2

Acid3 reveals broken behavior in toFixed and toExponential

This section of the test fails miserably:

      if ((0.0).toFixed(4) != "0.0000" ||
         (-0.0).toFixed(4) != "0.0000")
        ok = false;
      if ((0.0).toExponential(4) != "0.0000e+0" ||
         (-0.0).toExponential(4) != "0.0000e+0")
        ok = false;

I can't imagine this is intentional.  Current behavior:

(0.0).toFixed(4)
0.0000
(-0.0).toFixed(4)
0.00-0
(0.0).toExponential(4)
NaN
(-0.0).toExponential(4)
NaN
