Build, test, and debug regular expressions
This regex matches 2D coordinate pairs enclosed in parentheses, such as `(42, -3.14)` or `(+100, 200)`. It explicitly disallows leading zeros by using a negative lookahead, meaning values like `0`, `0.5`, or `05` will fail to match. It is useful for validating strict mathematical or geographical coordinate formats where standard decimal numbers without leading zeros are required.
