How to Hide Decimal Format in Custom Number Fields

Hi everyone, I noticed that the custom fields for numbers are now in a decimal format - is there any way to hide this?

For me: It is harder to read in the interface
For my subscribers: I use the merge tag for a custom field with a number in all my emails to show how many ‘points’ subscribers have - I don’t want to display 100.0 points, for instance

Let me know if I can toggle the format of the number somewhere, thanks 🙏
