 Description

Hi! The title says it all. This can lead to serious calculation errors if the user relies on SMath to detect the use of undefied variables. But it gets detected if the expression uses Numeric Optimization...

Fixed.

Yes, Davide. You're right.

Thank you!

I see a couple of issues for edgi cases (in red in the attachment); in all other cases shouldn't be an issue (if i'm not wrong).

What version of SMath Studio do you use?

In latest builds both Numeric and Symbolic optimizations will ignore undefined variables multiplied by zero. It is by design.

Please also describe what kind of serious calculation errors you expect because of this behavior?
