jquery find integer inside string

You probably shouldn't use JQuery for that; you should use built-in Javascript regular expression support. In this case your regular expression might look like:

var result = /\d+(?:\.\d+)?/.exec(mystring);

The official reference for this is at https://developer.mozilla.org/en/Core_JavaScript_1.5_Reference/Objects/RegExp .
