Find number of decimal places in decimal value regardless of culture

Question

I'm wondering if there is a concise and accurate way to pull out the number of decimal places in a decimal value (as an int) that will be safe to use across different culture info?

For example:
19.0 should return 1,
27.5999 should return 4,
19.12 should return 2,
etc.

I wrote a query that did a string split on a period to find decimal places:

int priceDecimalPlaces = price.ToString().Split('.').Count() > 1                    ? price.ToString().Split('.').ToList().ElementAt(1).Length                    : 0; 

But it occurs to me that this will only work in regions that use the '.' as a decimal separator and is therefore very brittle across different systems.

Answer 1

I used Joe's way to solve this issue :)

decimal argument = 123.456m; int count = BitConverter.GetBytes(decimal.GetBits(argument)[3])[2]; 

Answer 2

Since none of the answers supplied were good enough for the magic number "-0.01f" converted to decimal.. i.e: GetDecimal((decimal)-0.01f);
I can only assume a colossal mind-fart virus attacked everyone 3 years ago :)
Here is what seems to be a working implementation to this evil and monstrous problem, the very complicated problem of counting the decimal places after the point - no strings, no cultures, no need to count the bits and no need to read math forums.. just simple 3rd grade math.

public static class MathDecimals {     public static int GetDecimalPlaces(decimal n)     {         n = Math.Abs(n); //make sure it is positive.         n -= (int)n;     //remove the integer part of the number.         var decimalPlaces = 0;         while (n > 0)         {             decimalPlaces++;             n *= 10;             n -= (int)n;         }         return decimalPlaces;     } }
