Stop regex from removing decimal points

In my equation, I'm trying to remove the first word that appears after a specific word that I have mentioned in the regex code. For example:

In the sentence:

Hello my name is Roger

I'm extracting the word "Roger" with this regex:

Regex reg3 = new Regex("is\\s\\w+");
MatchCollection match3 = reg3.Matches(result);
foreach (Match match in match3)
{
    var val = match.Value;
    val = val.Replace("is", "");
    val = val.Trim();
}

But in a case such as this:

My answer is 3.05

and when I apply the same regex, I end up with this:

3

That is because the regex removes all characters after the "is", how do I change the regex so that it in a case such as what I mentioned above, it keeps the decimal number as it is and prints 3.05?

It stops after printing the first number because the following . is not a word character. To match also the literal dot, you need to put \w and . inside a character class.

Regex reg3 = new Regex("is\\s[.\\w]+");

OR

Regex reg3 = new Regex(@"is\s[.\w]+");
