Currency
|
| Expression |
^(?!\u00a2) #Don't allow cent symbol
\p{Sc}? #optional unicode currency symbols
(?!0,?\d) #don't allow leading zero if 1 or more unit
(\d{1,3} # 1 to 3 digits
(\,\d{3})* # if the is a comma it must be followed by 3 digits
|(\d+)) # more than 3 digit with no comma separator
(\.\d{2})?$ # option cents |
| Description |
This regex validates Currency. The base monetary unit (ex. US dollar) followed by option two digit cent denomination. Base unit can't have leading zero. Comma's are optional on base units. Note: Your regex engine must support the \p character class to use this. For example this will work in .net but not javascript which doesn't support \p Also the ¢ is removed from the match by force. Any other cent symbol would need to be added to the exclude to not match. |
