Localized Numbers

DDMathParser 2.0 adds support for parsing localized numbers. The most straight-forward way to parse a localized number is to pass the appropriate NSLocale into the Expression initializer.

There are some caveats to be aware of when parsing localized numbers:

• localized number parsing replaces the default number parsing
• scientific notation is not supported for localized numbers
• only the numbers are localized; no attempt is made to localize operators or directionality
• numbers are greedily matched. If you're parsing with a locale where , is the decimal separator, then sum(1,2,3) is interpreted as 1.2 + 3.
• whitespace is interpreted as being significant. For example, sum(1, 2, 3) is interpreted as 1 + 2 + 3.
