Masking Currency for Regular Expression in C#

just a little help on how to mask number to make proper currency value in Regular Expression with comma.. i made it this far..

 ₱\d*\.\d{2}

how to mask it with comma for every 3 digits? :)

thanks in advance..

Seeing as you have to use regex, here is your answer:

₱(?>\d{3},)*\d{1,3}(>?\.\d{1,2})?$

This will accept:

• ₱10
• ₱100
• ₱100,1
• ₱1.1
• ₱100,512,423.15
