This is because you use doubles for storing your values. You could use Math.Round to round those to the nearest integer.

trying to print the diff between the upper and lower bands

You do a doublevalue.ToString() call in your code. In C#, ToString can take a specific format string that shows how it should be output.

So:
double mynumber = 1.234567890;

Print("my number is: " + mynumber.ToString("F2", CultureInfo.InvariantCulture);

... will output a fixed point number with two decimal places to the right of zero. (F3 = 3 decimal places, etc, etc.)
