How do you display the answer in as a decimal?

Question

This code calculates the average of an array of integers. I know the answer is 6.88, but I cannot get it to display this way.
I have tried using the following data types:
integer, double, float, long, and, decimal. I have also tried using memberList.Format(0.00);
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace SoloLearn
{
class Program
{
class CalcAverages
{
}
static void Main(string[] args)
{
int[] memberList = new int[8] { 2, 4, 9, 12, 3, 2, 15, 8};
Console.WriteLine(memberList.Sum());
double average = memberList.Sum() / memberList.Length;
Console.WriteLine(average);
}
}
}

Answer 1

Emma as you have used int data type that's why precision value is rounded. Use float instead of the int data type
float[] memberList = new float[8] { 2, 4, 9, 12, 3, 2, 15, 8};

Answer 2

Thanks Mohit. I thought it would be something obvious 🙂
