C# get digits from float variable

Question

I have a float variable and would like to get only the part after the comma, so if I have 3.14. I would like to get 14 as an integer. How can I do that?

Answer 1

To suggest something different than the others, an extension method (with a method similar to David's):

public static int GetDecimalAsInt(this float num)
{
    string s = n.ToString();
    int separator = s.IndexOf(System.Globalization.CultureInfo.CurrentUICulture.NumberFormat.NumberDecimalSeparator);
    return int.Parse(s.Substring(separator + 1));
}

// Usage:
float pi = 3.14;
int digits = pi.GetDecimalAsInt();

Edit: I didn't use the "best" answer, because it omitted the hardest part, which is converting an arbitrary decimal number, and did not work for negative numbers. I added the correction requested in David's answer.
