Regular expression for price validation

Any of the above did not work for me. Only this works for me

^([0-9]{0,2}((.)[0-9]{0,2}))$

^\d{0,8}(\.\d{1,4})?$

You can make the entire decimal optional

You can try this:

^\d{1,8}(?:\.\d{1,4})?$

^[1-9]\d{0,7}(?:\.\d{1,4})?$

If you don't want to have a zero as first digit.

You can allow this if you want: (.1234)

^[1-9]\d{0,7}(?:\.\d{1,4})?|\.\d{1,4}$
