Raising a negative number to a power

[paravantis]

It appears that the use of parentheses in the following code gives an invalid delimiter error

Uses "Console"
printl (-2)^2
WaitKey

while the following alternative runs well

Uses "Console"
printl -2^2
WaitKey

On the other hand, the following version gives the wrong answer!

Uses "Console"
printl -(2)^2
WaitKey

So, something is not right with parsing such numerical expressions.
