    "Round Up" for tax calculation.

    Asked by jssales on July 26, 2016 at 03:59 PM

    Hello, I need to calculate tax on a form and I'm having some issues. However, due to the nature of the system I cannot use the PO form or any other type of payment form.

    TotalOrder * .07275 = Output

    TotalOrder + Output = Cost

    If I change the Cost to 2 decimal places the form does not "round up" for tax calculations.


    9 * .07275 = .65475

    9 + .65475 = 9.65475 (cost)

    If I tell the system to format using 2 decimal places I get 9.65 and I actually need it to read 9.66

    Can you think of any way to change this so it calculates properly? Thank you.

    It is actually calculating properly, the round up is done when the next decimal number is greater than 5, and in this case "9.65475" stays at 9.65 because the next decimal number is 4.

    If you want to, you could add "+ 0.01" to the calculation. Let us know if you need more help.

    Thank you, you're correct, this one works. I tested so many of them, I cannot remember which one it didn't work on. I'll give it a go and see if I run into another issue. Thank you for the quick reply!
