Round a signal in simulink?

Can I round a signal in simulink to the third decimal place?

The round fuction block rounds to the nearest integer, and when I try and use round(var) in a user defined matlab function it works, but round(var,3) errors out.

I feel like this should have a very easy solution, which is currently evading me.

this is a dirty trick but it works

first multiply by 1000, round , then multiply by 1e-3
