I patched NumericEvaluator to use the system locale to pick the right
decimal separator character. I have tested it on Windows and Linux, no
issues found. In my opinion it is ready to be merged and could be a nice
bonus for v5. Sincerely, I love this feature, so I might be a bit biased.

Cheers,
Orson
