Testing 1.21.0-beta1 mathematical expression with negative numbers

[UUoocl]

Thank you for the super useful plug-in.
The new release 1.21.0-beta 1 worked with my previous macros on Windows 11.
The new math expression worked with positive numbers, but negative numbers returned an error.
In my test, a variable named "neg1" stores a negative number "-1". The "neg1" variable is referenced by another variable set to mathematical expression. The error "failed evaluate expression "-1+1": is returned.

Is it possible to calculate a mathematical expression that includes a negative number?

Thank you

I will look into it and report back if it is something can be implemented easily :)

Update:
Instead of trying to reinvent the wheel I now settled on using the "exprtk" library.
This should resolve your issues.

A build with this change should be available here in a few minutes:

Let me know if you run into any issues! :)

Thank you very much! This update solved the issue.
I tried some of the functions available in the "exprtk" library, and those worked as expected too.

This is a fantastic update that will enable new creative options. Well done!
