Hi,

First example

------------------------------------------------------------------------------------------------------------------

dim $a,$b,$c

$a=1.00045

$b=1.00021

$c=$a-$b

run("notepad.exe")

WinActivate('Untitled - Notepad')

WinWaitActive('Untitled - Notepad')

send("$c=")

send($c)

-------------------------------------------------------------------------------------------------------------

Output

$c= 0.000240000000000018 wtf, why not 0.00024

Second example

-------------------------------------------------------------------------------------------------------

dim $c

$c=987654321.123456789

run("notepad.exe")

WinActivate('Untitled - Notepad')

WinWaitActive('Untitled - Notepad')

send("$c=")

send($c)

---------------------------------------------------------------------------------------------------------------

Output

$c=987654321.123457 , why not 987654321.123456789

Do you know how to fix this?

Hi. Floating point maths problems. AutoIt can't solve this. Same problem in C++, C#, VB, etcetera.

Thx Managar. Seems all my programs must not have any floating points. Its sad.

You can use floating points. You just have to deal with the fact that floating point numbers will have some issues. There are a number of interesting things about floating point values.
