[Octave-bug-tracker] [bug #54491] Order of evaluation of power with unitary operators

[anonymous]

Follow-up Comment #2, bug #54491 (project octave):

function out = test()
        global a;
        a = 2;
end
global a;
a = 1;
z=[7 8]
z(a) ^=- test();


I don't have MATLAB but it should work:


function out = test()
        global a;
        a = 2;
end
global a;
a = 1;
z=[7 8]
z(a) ^- test();
a


Evaluation order from the left to right  prints 2 the order from the right to
left it prints 1.
I think precedence, associativity and order of evaluation should be exactly
defined so a programmer using that rules knows how to program with the
programming language.
