You really could have googled for "regular expression number" to find an
answer like the "//Function to test whether the string is valid number or
not" section at
http://www.c-sharpcorner.com/Language/RegExpressionSample1.asp

You didn't mention if number formats like 1.23e34, which is valid for a
floating-point number, or negative numbers were acceptable for your purpose.
