Solution 3

Hi,
If you want to make sure the text contains only digits use a simple ^\d+$ or ^\s*\d+\s*$ to allow some spaces at the beginning and end.
To allow negative numbers:^-?\d+$ or ^[+-]?\d+$ to allow numbers like +12
For decimal numbers: ^[+-]?\d+(\.\d+)?$ (this will allow 0.54 but not .54)
This one will allow things like .54
^[+-]?(\d+(\.\d+)?|\.\d+)$
