Average function without overflow exception

Question

.NET Framework 3.5.
I\'m trying to calculate the average of some pretty large numbers.
For instance:

using System;
using System.Linq;

class Program
{
           


        

Answer 1

Here is my version of an extension method that can help with this.

    public static long Average(this IEnumerable longs)
    {
        long mean = 0;
        long count = longs.Count();
        foreach (var val in longs)
        {
            mean += val / count;
        }
        return mean;
    }
