using System;

class Decompose {

  /* Decompose a floating-point value into its

     integer and fractional parts. */

  public int GetParts(double n, out double frac) {

    int whole;

    whole = (int) n;

    frac = n - whole; // pass fractional part back through frac

    return whole; // return integer portion

  }

}

class UseOut {

  static void Main() {

   Decompose ob = new Decompose();

    int i;

    double f;

    i = ob.GetParts(10.125, out f);

    Console.WriteLine("Integer portion is " + i);

    Console.WriteLine("Fractional part is " + f);

  }

}

The output from the program is shown here:

Integer portion is 10

Fractional part is 0.125

The

GetParts( )

 method returns two pieces of information. First, the integer portion of
