Issue Type "Number", decimal

[Tiziana Pisenti]

I created a Custom Field Type "Number". I want to configure the field, so only one decimal can be entered in this field.

so only x.y and not x.yz

How can I do that?

It is not possible to restrict.

However, via automation, you can convert the value to floor and ciel.

@Tiziana Pisenti - You can add a "Regular Expression Check" validator on the workflow transitions (where ever the field validation is required) to validate the format entered in the field.

Use the following regular expression to allow numbers with only one decimal place:

^\d+(\.\d{1})?$

This validation will only apply when creating or transitioning the issues.
