currency regex with decimal allowed with 0

With reference to my previous question currency regex

I want to add an condition, i want to allow decimal only if it starts with 0

example

0.25 should be allowed 1.25 not allowed

current regex is as following

/^(?:\d{1,3}(?:,\d{3})+|\d+)(?:\.\d+)?$/

which matches comma trailing etc.

This will match all the currency matches from before without decimals or decimals with 0.x*

/^((?:\d{1,3}(?:,\d{3})+|\d+)|(?:0\.\d+))$/

If you only want to match 0.xx instead of an arbitrary number of decimal places use

/^((?:\d{1,3}(?:,\d{3})+|\d+)|(?:0\.\d{2}))$/

This one changes \d+, one or more digits, to \d{2}, exactly 2 digits.
