Review Comment:
   Seems there is 5 (or 3) of these, how about using suberror classes here:
   INVALID_NUMBER_FORMAT.CURRENCY/EMPTY/SEPARATOR
   
   Or:
   INVALID_NUMBER_FORMAT_CURRENT
   ...
   
   Also I think the two flavors for SEPARATOR and CURRENCY each can be merged.
   
   Currency characters must appear before the decimal point and any digits in the number format
