confirmed

Parser.parse("a-b^2", scope);
a.setValue(3);
b.setValue(6);

produces -33

Parser.parse("3-6^2");

produces 39

Parser.parse("3-(6^2)");

produces -33

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

This should be easy to pull into parsii itself.

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

-3^2 = -3 * -3 ≠ -9

According to Wikipedia: "In written or printed mathematics, the expression −3^2 is interpreted to mean 0 − (3^2) = − 9".
