To find the integer portion of a decimal or double number, you need to use `System.Math.Truncate(Decimal or Double value)`

method as shown in below snippet:

decimal pi = (decimal)System.Math.PI; //pi = 3.14159265358979 decimal dec = System.Math.Truncate(pi); //dec = 3 double trouble = 5.555; double dbl = System.Math.Truncate(trouble); //dbl = 5
