Printing numbers after decimal point

How can i print the numbers of a float/double variable after the decimal point? For example for 435.5644 it will output 5644.

EDIT: reference to another question (http://stackoverflow.com/questions/4512306/get-decimal-part-of-a-number-in-javascript) You can do the following:

double d = 435.5644;
float f = 435.5644f;
Console.WriteLine(Math.Round(d % 1, 4) * 10000);
Console.WriteLine(Math.Round(f % 1, 4) * 10000);

That will give you the integer part you looking for.

Best is to do it as Aghilas Yakoub answered, however, here below another option using string handling. Assuming all amounts will have decimals and that decimal separator is a dot (.) you just need to get the index 1.

double d = 435.5644;
Console.WriteLine(d.ToString().Split('.')[1]);

float f = 435.5644f;
Console.WriteLine(f.ToString().Split('.')[1]);

Otherwise you may get a Unhandled Exception: System.IndexOutOfRangeException.

try with 

fraction = value - (long) value;

or :

fraction = value - Math.Floor(value);

You can try the following:

  double d = 435.5644;
  int n = (int)d;

  var v = d - n;

  string s = string.Format("{0:#.0000}", v);

  var result = s.Substring(1);

result: 5644
