How do I change the quantity of numbers shown after a comma

Hello people,

simple question, maybe noobish but, is there a way to set a number like 0,123456789 to 0,123 so that only the first three numbers are shown after the comma?

cheers and thanks for helping!

I like construct2 very much, but this community is what makes the software so nice to use!

Thank you both for helping me with this. I used it, for my counter to show the milliseconds.

Since the image is no longer online here is the calculation which was shown in the picture:

round(N * 100) / 100

for 2 decimal places, or 1000 for 3 decimal places,...
