Split decimal variable into integral and fraction parts

Question

I am trying to extract the integral and fractional parts from a decimal value (both parts should be integers):

decimal decimalValue = 12.34m; int integral = (int) decimal.Truncate(decimalValue); int fraction = (int) ((decimalValue - decimal.Truncate(decimalValue)) * 100); 

(for my purpose, decimal variables will contain up to 2 decimal places)

Are there any better ways to achieve this?

Answer 1

       decimal fraction = (decimal)2.78;         int iPart = (int)fraction;         decimal dPart = fraction % 1.0m; 

Answer 2

Try mathematical definition:

var fraction = (int)(100.0m * (decimalValue - Math.Floor(decimalValue))); 

Although, it is not better performance-wise but at least it works for negative numbers.
