Need help with: Define a Divide method that takes two int values as parameters, and returns the results as double value

Hi!

I'm a bit stuck on the "Let's practice type conversion. Define a Divide method that takes two int values as parameters, and returns the result of dividing them as a double value. For example, Divide(5, 2) should return 2.5. (Normally, a method like this should probably take double parameters, but we want to practice converting values from int to double.)

You'll need to convert each of the int values to double before performing the division operation, so you don't lose the fractional portion of the result." problem.

The code is as follows

// YOUR CODE HERE: Define a Divide method! public double divide(param1, param2) { double param1 = (double); double param2 = (double); return (param1 / param2);
}

static void Main(string[] args)
{
    // This should print "2.5".
    Console.WriteLine(Divide(5, 2));
    // This should print "3.3333333333..."
    // (Or a value close to that, since it can't be
    // infinitely precise.)
    Console.WriteLine(Divide(10, 3));
}

I know my method is not correct but I wanted to show my general idea. I've looked at previous lectures and see similar code but I can't quite adjust it.

You've got the right idea, but have a few syntax issues. Here's a few hints:

  • remember to indicate the types of the parameters
  • based on how it is being called, this would be a static method
  • you'll need to give your internal variables different names from the parameters
  • the casts should be followed by the parameter names

but whats it look like

Jonathon, if these hints don't fit your situation, start a fresh new question and post your own code in it. Be sure to use Markdown formatting to preserve the appearance (it was unfortunately omitted in the example here).

using System;

class Program {

// YOUR CODE HERE: Define a Divide method!

static double Divide(int param1, int param2) {
return ((double)param1 / (double)param2); }

static void Main(string[] args) {

Console.WriteLine(Divide(5, 2));

Console.WriteLine(Divide(10, 3));

} }

I solved this a few days ago. Thanks for the help and feedback. :-)

Thanks! I'll keep working on the problem. :-)
