How can I get a count of the total number of digits in a number?

Question

How can I get a count of the total number of digits of a number in C#? For example, the number 887979789 has 9 digits.

Answer 1

Answers already here work for unsigned integers, but I have not found good solutions for getting number of digits from decimals and doubles.

public static int Length(double number)
{
    number = Math.Abs(number);
    int length = 1;
    while ((number /= 10) >= 1)
        length++;
    return length;
}
//number of digits in 0 = 1,
//number of digits in 22.1 = 2,
//number of digits in -23 = 2

You may change input type from double to decimal if precision matters, but decimal has a limit too.
