[Octave-bug-tracker] [bug #33304] power operator precedence and direction

[Rik]

Follow-up Comment #3, bug #33304 (project octave):

Verified in Matlab.  Octave should be processing left-to-right and not
breaking off when it sees a unary symbol.  This applies to either '+' or '-'.


2^+4^3
ans =  1.8447e+19


because this is parsed as 2^(+4^3).

For Matlab, the logical not operator (~) is at the same level of precedence as
the unary operators and therefore might need to be processed in the same
manner as +/-.

Demonstration code:


2^~0^2 = 2
because Octave parses this as
2^(~0^2) == 2^(~(0^2)) == 2^(~(0)) == 2^(1) == 2
It should probably be parsed as
(2^~0)^2 == (2^1)^2 == (2)^2 = 4
