Hello, 

I have some complicated calculations which result in a lot of 1e(-7) or even 1e(-12). These numbers greatly complicate the expersisions without adding any benefits. 

How do I instrcut Maple to round the calculations to the nearest decimal precision?

I tried "Digits" and "Rounding" and "interface(precisiondisplay)" but none of them get rid of something like 3.343^(-12)* expr. 

I still see such infistimal terms showing up. 

If you're wondering, I am exporting these symbolic terms to Matlab to be used as optimization functions. So, having these extra terms add unnecessary optimization steps. 

Thanks.
