Is it possible to allow decimals in the card value section under the form?

we created the landing page on unbounce.com. Please advise on the following:

  1. Is it possible to allow decimals in the card value section? Currently only whole numbers are allowed, we did create a javascript to not allow users to enter the value but it seems some are still coming thru with on mobile devices

(At the moment users cannot enter a value of $ on the card value section but we want he user to be able to add decimals such as 1.00, 1.01,1.10 etc
So if it’s something that can be fixed from the code - just let me know
OR, if this is something that can be fixed on the settings - that would be perfect)

  1. On mobile devices we need to not allow the value/symbol on the card value section basically when you enter it disappears which is good on desktops, but we need to make the same for mobile devices where symbol $ is not allowed and decimals is allowed instead of just whole numbers
