[FIX] i attach a SqNumberParser class that can fix: - all these weird behaviours - reading of floating point numbers (round to nearest floating point value) - reading of -0.0 ( http://bugs.impara.de/view.php?id=3482 [^] ) First load the two patches correcting: Integer>>asFloat http://bugs.impara.de/view.php?id=3564 [^] and Fraction>>asFloat at http://bugs.impara.de/view.php?id=3568 [^] TODO: branch SqNumberParser on Number>>readFrom: TODO: add a specific NumberParserError or NumberParserException With the patch, you cannot read '3.e-3' nor '.3e-3' anymore, but these weren't identified as proper squeak syntax... |

This is faster and better than the current number parsing in class Number. I have provided a cleanup to the current parser in Mantis 0003993, but I really think that this NumberParser is a better approach. These change sets can be added to the current Squeak image with no impact on the existing parser, so this would be a safe change. |
