I have this code String RateBuy7 = Regex.Match(Response, @"</a></td><td>([0-9]+\.+[0-9]+)</td><td>").Groups[1].Value; I need to find a number that could be like int ("12") and be like double ("12.5"). How to do it right? Because that code ([0-9]+\.+[0-9]+) have only found float numbers. But those numbers aren't always float. Help me please//

Normally you want something that does HTML parsing for you, but if you are going to have to use a regex, something like this should work:

</a></td><td>\d+(\.\d+)?</td><td>

You want that first set of numbers, and then optionally a period followed by some numbers. This should do the trick.

To match integers as well as "rational numbers" you could use this code:

</a></td><td>([0-9]+\.?+[0-9]+)</td><td>

Notice the question mark behind the dot. This way the dot is needed zero or once for matching.

I can recommend https://regex101.com for testing.
