I have fixed this issue in my fork. You can see what change is required here: invesdwin/invesdwin-util@152afa3

I still have this issue with parsii-4.0, even with the sources package.
How can I get the correct version of parsii ?
What is mpobjects/bdparsii ?

Is it normal that : "1+(-3^2)" still gives 10, instead of -8 ?
More simpler: -3^2 gives 9, instead of -9
from parsii.
-3^2 = -3 * -3 ≠ -9
from parsii.
According to Wikipedia: "In written or printed mathematics, the expression −3^2 is interpreted to mean 0 − (3^2) = − 9".
