[02/03] Decimal

Suppose I am using a double variable for storing the grade point average. I want that there are two digit after the decimal point. How we can do.

Thanks

If you want to display a Double value as a string with two decimal places then you use:

myString = myDouble.ToString("n2")

If you actually want to round the Double value itself to two decimal places then you'd use:

myDouble = Math.Round(myDouble, 2)

Note that Math.Round uses the normal method to round the value up or down. If you actually want to truncate then it is a little more complex, but still not difficult.
