2 solutions

Solution 1

Try:

^[1-9](\d{0,2})(,\d{3})*(\.\d{3})$

^([1-9](\d{0,2})|0)(,\d{3})*(\.\d{3})

If you want to work with regexes, then get a copy of Expresso [^] - it's free, and it examines and generates Regular expressions.

[edit]:doh: - I forgot "0.123", the original expression wouldn't allow it. - OriginalGriff[/edit]

My 5! This validates EN-US formatted floating point numbers with exactly three decimal digits.

Reason for my vote of one: Please read the question. The OP wants comma delimited thousands, not just digits.

Andreas Gieriet 26-May-13 10:18am

I agree with OriginalGriff: not answering the question and the expression . is also accepted. In addition, there is no limitation mentioned to 9 integral digits.
