Replace the "comma" character with the "period" character

Certified Associate Developer

Hi all

I am following Appian standard in using a text field on a form with which to populate a decimal field in my rule input.

Appian standard behavior for a decimal field is that if a comma symbol is used to indicate a decimal place, the symbol is automatically removed and the value is then displayed with no separation.

Example:

The user enters 650,52

On refresh, the comma disappears and the value saved in the rule input is now 65052

If one uses the period symbol, the value is displayed correctly, thus 650.52, and the value is saved correctly into the rule input

We cannot assume that the target group of users will understand the distinction between the symbols, so we need to put in some sort of validation in order to avoid the issue.

I have tried using the cleanwith() function, but am unable to make it work.

I would like to be able to do one of the following (in order of preference):

  1. have the comma symbol automatically replaced with the period symbol
  2. set the field up so that it is impossible for a user to enter a comma symbol
  3. set up a validation rule that recognises a comma symbol and requires the user to input a period symbol

Any help will be greatly appreciated!

  • On what Marcel suggested, if you try to insert a number having 2 commas or having a comma and a dot as separators then it's not working properly. So that needs some improvements on what number formats can be accepted. Also, because the component is a textField, it can accept letters also and not only numbers. So you have to use the cleanwith() function to allow only numbers, periods, and comma characters to be inserted.

    Also, an OOT, are you suggesting your answer as a correct answer to your own question? That's bizarre man LOL
