Average of 3 long integers

Question

I have 3 very large signed integers.

long x = long.MaxValue;
long y = long.MaxValue - 1;
long z = long.MaxValue - 2;

I want to calculate th

Answer 1

NB - Patrick has already given a great answer. Expanding on this you could do a generic version for any number of integers like so:

long x = long.MaxValue;
long y = long.MaxValue - 1;
long z = long.MaxValue - 2;

long[] arr = { x, y, z };
var avg = arr.Select(i => i / arr.Length).Sum() 
        + arr.Select(i => i % arr.Length).Sum() / arr.Length;
