How to add "-" as unary operator with lower precedence than "^"

[karenpb]

Hi,

I am running into the issue that when interpret the expression "2^-1^2^3", the returned expression tree takes precedence as ((2^(-1))^2)^3. But the expectation is 2^(-((1^2)^3)). I realize that in this case the unary operator "-" takes higher precedence than "^".

Is there any way that I can assign "-" with precedence lower than "^"?

I have tried to call jsep.addUnaryOp('-'); but it doesn't seem to change the default precedence.
