Pow()

[James]

Hi all,

Does anyone have a mathematics, Pow() function?

Thanks,

James

Edit:

This is right isn't it?

Func Pow($x, $y)
    Return $x ^ $y
EndFunc

According to http://www.cafeaulait.org/course/week4/40.html it is... muttley

[James]

Woo. I never needed this until now muttley

Shouldn't these basic math functions be added to the Math UDF? I mean, it's maths and so is the function. I am sure there are loads more like LambertW which should be added etc.

Pow doesn't need to be added because the operator has been there for a LONG time.

^, just realised.

So you didn't read the help file from front to back like everyone else?

For those of you who doesn't trust fancy mathematical operators like '*', '/' or '^' I've made 3 unsigned integer functions that only uses the '+' and '-' signs.

MsgBox(0,"2*3",_Multiply(2,3))
MsgBox(0,"9/3",_Division(9,3))
MsgBox(0,"5^2",_Pow(5,2))



Func _Pow($f1,$f2)
    Local $answer=1
    For $i=0 To $f2-1
        $answer=_Multiply($answer,$f1)
    Next
    Return $answer
EndFunc


Func _Multiply($f1,$f2)
    Local $answer=0
    For $i=0 To $f2-1
        $answer+=$f1
    Next
    Return $answer
EndFunc


Func _Division($f1,$f2)
    If $f2=0 Then Return "1.#INF"
    Local $answer=0
    While $f1>0
        $answer+=1
        $f1-=$f2
    WEnd
    If $f1<0 Then
        $answer-=1
    EndIf
    Return $answer
EndFunc

No see, I knew it is there because I have used it before, but... I forgot about it today!
