How to remove .0 from reports?

Very new to math functions, so I’m sorry if this is obvious.

I have a calculated property DefenceMultiplierActual calculated as Math.pow(2,DefenceMultiplier)

The problem is that when reporting this, the report $DefenceMultiplierActual$ always includes .0, despite the fact that DefenceMultiplier is always an integer.

How can I fix this?

First thing that comes to mind is to make DefenceMultiplierActual Math.round(Math.pow(2,DefenceMultiplier)), instead.

Cheers!
