Regular expression patterns with data types?

I am wondering if a regex can contain a placeholder for a data type, for example 'double'. In particular, I want to check if a certain input string contains a 'double' number:

string input = "this is a double: 2.25";

// Is there such a thing similar to this???
Regex rx = new Regex("{double}");
Match m = rx.Match(input);

...and m would contain 2.25 (cos it's a double).
