Regex For Dollar Amount Greater Than $500

I'm trying to match dollar amounts greater than $500. Signals that it's a dollar amount would be a dollar sign or a decimal point with 2 zeros. I put my try so far plus sample dat

Solution 1:

Seems weird to validate a number greater than with a regular expression, but it would be something like this

^\$([5-9]\d{2}|[1-9]\d{3,})\.\d{2}$

Uses an or to do the validation of the range.

• [5-9]\d{2} < matches range from 500 to 999
• [1-9]\d{3,} < matches 1000 +
