    Hi - I've created a calculation form in JotForm:


    However I can't figure out how to get the calculation to not have a decimal place, i.e. be £1000 not £1000.00


    Could anyone help?

    You can remove it by unchecking the following option in the calculation wizard.

    In the calculation wizard, click the 3 dots to open the calculation options

    Then uncheck "Show empty decimal places".

    Hope this helps!

    Hi - sorry I should have said, the form isn't using the inbuilt JotForm calculation function, it's other code.

    I'm not really sure why you are using a script to do calculations here and why the form is embedded on your website using the full source code. However, I presume this is the script that responsible for the calculation:


    Your script uses toFixed() function which declares a decimal point to the said value. Here it is set to 2 which is why you are getting 2 decimal places. If you want to remove the decimal places, then you can try using the following functions:

    Math.trunc() (truncate fractional part, also see below)

    Math.floor() (round down)

    Math.ceil() (round up)

    Math.round() (round to nearest integer)


    You can also contact the developer who created the script to have a more better approach.

    If in case you will using JotForm's own features for calculations, you can check the following guides: 


    I hope that helps.

    Thanks I just need to amended the toFixed to 0, rather than 2.

    I built the form ages ago using JotForm because it was simple for the conditional logic, and it's the source code version because I pass the course fee through the URL (it's a College website) that has fees for diff courses.

    As my colleague mentioned, you can contact the developer to amend the code. And if you want you can use JotForm functionalities, you can also set the payment integration to accept a user defined amount rather then a fixed amount, and you can redirect results to external pages.
