To regex negative numbers and dashes, you can use the following regular expression pattern:
1
|
^[-]?d+$ |
Explanation:
- ^ : asserts position at the start of the line
- [-]? : matches an optional negative sign (-)
- d+ : matches one or more digits (0-9)
- $ : asserts position at the end of the line
This pattern will match both negative numbers (e.g. -1, -100) and positive numbers (e.g. 1, 100) with an optional negative sign at the beginning.
