Imaginary Numbers

[BALA]

I'm trying to find teh square root of a negative number. I have a script like this:

$x = Sqrt(-9)
MsgBox(0, "test", $x)

Though It keeps on producing "-1.#IND" but I'm expecting the imaginary number "3i"

Are imaginary numbers a limitation in the AutoIt language or am I just doing this the wrong way?

That i would guess... no normal scriptlangues knows imaginary numbers (as far as I know)

Man, what a drag. That ruins my idea for a program that will solve polynomials.

EDIT: I think I have a work around that I could use. Anyways, thanks for the help Sheville

If you think a little outside the box. Autoit can handle them. Just use arrays with two entries one for the real and one for the imaginary part. The only thing is that you have to use functions to manipulate the variables.

Func IVAdd(ByRef arg1, ByRef arg2)
    ;Possibly check that the array is size2 and is an array
    Local $ret[2]
    $ret[0] = $arg1[0] + $arg2[0]
    $ret[1] = $arg2[1] 0 $arg2[1]
    Return $ret
EndFunc

Not as nice and cool, and fast, as it is possible to do it in C/C++ but it works. You should probably be able to find libraries you could use to on the net.

EDIT: Typo
