Simple Calculator

[Guest]

I have not been doing much recently so i thought i should play around with variables a bit and do some math

Maths.au3

$1 = InputBox("Maths", "Number:", "")
$operation = InputBox("Maths", "+, -, *:", "")
$2 = InputBox("Maths", "plus Number:", "")
$plus = $1 + $2
$minus = $1 - $2
$times = $1 * $2
If $operation = "+" Then
MsgBox("", "Maths", "= " & $plus)
EndIf
If $operation = "-" Then
MsgBox("", "Maths", "= " & $minus)
EndIf
If $operation = "*" Then
MsgBox("", "Maths", "= " & $times)
EndIf

Maths.au3

There are a couple of ways to make a calculator that accepts more inputs, like typing "5*3" into one InputBox. The easiest by far is to use the Execute function. Take a look, see what you come up with Then look at GUIs as well and you'll be well on your way to making a fully functional calculator.

Calculator on a single line

Thanks this is so much better

$input = InputBox("Maths", "Enter an equasion", "")
$ans = Execute($input)
MsgBox("", "Maths", "Answer = " & $ans)

As you said-GUI...

I will just get started!

Indeed, you should consider at least a StringRegExReplace() to remove anything but the maths symbols and digits you want to allow.

OK i am working on that but in the mean time here is a gui!

#include <GUIConstantsEx.au3>

Local $file, $btn, $msg
GUICreate(" Calculator", 395, 30, @DesktopWidth / 2 - 160, @DesktopHeight / 2 - 45, -1, 0x00000018); WS_EX_ACCEPTFILES
$file = GUICtrlCreateInput("", 10, 5, 300, 20)
GUICtrlSetState(-1, $GUI_DROPACCEPTED)
$btn = GUICtrlCreateButton("=", 325, 5, 60, 20)
GUISetState()
$msg = 0
While $msg <> $GUI_EVENT_CLOSE
$msg = GUIGetMsg()
Select
  Case $msg = $btn
   ExitLoop
EndSelect
WEnd
$ans = execute(guictrlread($file))
MsgBox(4096, "Calculator", $ans)

Have fun!

Don't know how much fun I can have with a calculator, but thanks anyway.

But will it blend? Haha, no. Secondly, I improved your script a bit.

#include <GUIConstantsEx.au3>
Main()
Func Main()
Local $file, $btn, $msg
GUICreate("Calculator", 395, 30, @DesktopWidth / 2 - 160, @DesktopHeight / 2 - 45, -1, 0x00000018); WS_EX_ACCEPTFILES
$file = GUICtrlCreateInput("", 10, 5, 300, 20)
GUICtrlSetState(-1, $GUI_DROPACCEPTED)
$btn = GUICtrlCreateButton("=", 325, 5, 60, 20)
GUISetState()
While 1
  $msg = GUIGetMsg()
  Select
   Case $msg = $GUI_EVENT_CLOSE
    Exit (0)
   Case $msg = $btn
    GUICtrlSetData($file, Execute(GUICtrlRead($file)))
   Case Else
    ;;;
  EndSelect
WEnd
EndFunc   ;==>Main

Wow that's great!

I actually keep a list of calculators: http://code.google.com/p/m-a-t/wiki/Maths#Calculators

I couldn't resist playing this one out a little farther. This version works nicely (so did the first one).

Note that all of the code is like Lego blocks written by others. I just snapped the blocks together.
