Okay, practicing my coding skills (lol), I decided to make a little program that would figure the sales tax in with stuff. Anyways, I've come to the conclusion that it'd be a lot more accurate if it would round the total amount to the hundredths place. I believe it will be somethign with the math.round(number) deal, but I can't quite figure it out. Thanks. (the number is assigned to a string).
 
You first need to convert the string into a number which you can
work with, and then you can use the Round function to get it
to a certain decimal place. Consider this example:

Visual Basic: 
    Dim dNum As Double ' Number before rounding
    Dim dNumRounded As Double ' Number after rounding

    dNum = Double.Parse("14.52612") ' Turn the String into a Double

    dNumRounded = Math.Round(dNum, 2) ' Round it (the 2 is the # of decimal places to round)

    MessageBox.Show(dNumRounded.ToString) ' Shows the results (should be "14.53")

HTH
