For display only, use the F2 format string:

double test = 1.234567;

Console.WriteLine("1) test = " + test.ToString("F2"));
Console.WriteLine("2) test = {0:F2}", test);

For display only, use the F2 format string:

double test = 1.234567;

Console.WriteLine("1) test = " + test.ToString("F2"));
Console.WriteLine("2) test = {0:F2}", test);

The format strings round up if halfway between two numbers. Useful.

The Math.Round method rounds to the even number if halfway between two
numbers. Weird.

I think Math.Round always rounds to the even number. So if you have 23.5,
it rounds to 24. If you have 24.5, it rounds to 24.

I believe there is a third argument on the Round method for "midpoint
rounding" argument where you can tell it what to do.
