Validating Input String - Сообщения

What would be the best way to validate an input string in order to ensure it is a number and does not include any other characters?
Keep in mind that I'm referring to actual input in string form that is then converted into a number via str2num().

Here is a less compact solution, can be adapted to accept different characters.
(Positive/negative values can be allowed with an additional condition on the first character)

Near identical to Davide, this is how I would do it.
At least this is what I have done in QBasic long ago.
