Strings in a DataFrame, but dtype is object
...ta access. For example, consider how your computer might store an array of 32-bit integers, [3,0,1].
If you ask your computer to fetch the 3rd element in the array, it'll start at the beginning and then jump across 64 bits to get to the 3rd element. Knowing exactly how many bits to jump across is w...

Average of 3 long integers

I would suggest that a good way of dividing a 32-bit unsigned value by 3 is to multiply by 0x55555555L, add 0x55555555, and shift right by 32. Your divideby3 method, by comparison, looks as though it would require many discrete steps.

Try this:
int x = Int32.Parse(TextBoxD1.Text);
or better yet:
int x = 0;
