I'd like to make a basic math windows script 100/(A/B+1) into which I can quickly type in values and get a result.
Thanks.
Can AHK do simple maths programs? Topic is solved
Re: Can AHK do simple maths programs?
Yep, it sure can.

Re: Can AHK do simple maths programs?
There is a pretty slick way to handle this using an ActiveX control that already knows how to evaluate math expressions that are represented as a string.daithy wrote:I'd like to make a basic math windows script 100/(A/B+1) into which I can quickly type in values and get a result.
Thanks.
Code: Select all
Gui, Add, ActiveX, vpwb, Shell.Explorer
pwb.Navigate("about:<!DOCTYPE HTML><meta http-equiv=""X-UA-Compatible"" content=""IE=Edge"">")
Math := pwb.Document.parentWindow
MsgBox, % Math.Eval("2+3")
A := 100
B := 2
MsgBox, % Math.Eval(100/(A/B+1)) ; this is actually being evaluate by AHK and is not a good example as pointed out by Flipeador
Exp = 100/(%A%/%B%+1)
MsgBox, % Exp " = " Math.Eval(Exp)

Re: Can AHK do simple maths programs?
I think it should be Math.Eval("100/(" . A . "/" . B . "+1)") instead of Math.Eval(100/(A/B+1)).FanaticGuru wrote:There is a pretty slick way to handle this using an ActiveX control that already knows how to evaluate math expressions.
interesting way to do it

Re: Can AHK do simple maths programs?
Yea, right after I posted, I noticed I did not do very good examples. Editted while you were posting to do better. But hopefully I got the basic technique across.Flipeador wrote:I think it should be Math.Eval("100/(" . A . "/" . B .

You can pass the ActiveX a totally math expression string but you can not pass it an AHK variable in a string. Any AHK variables have to be resolved by AHK before sending the math expression string to the ActiveX control.

In some languages, the thousand separator "." sign is the "," sign in some languages. How can we do the correct calculation in any case?

Thanks. Very good. Autohotkey is a very rich language thanks to you and other developers.
