How to create Regex for Int and Float value using Swift 4.2?

Question

My scenario, Here I am trying to validate my pricing textfield should support and allow only Integer and double or float values. I mean numbers with fullstop.

Below regex format workin for integers but if value float or double its not allowing.

My Regex:

^[0-9]+(?:,[0-9]+)*$

Expected output : 123 and 123.0 // It should allow both.
