printf()

[xerox]

I am trying to use printf() but it doesn't seem to work correctly?

#AutoIt3Wrapper_Change2CUI=y
#AutoIt3Wrapper_UseX64=y

#pragma compile(Console, true)
$float1 = 0.9375
$float2 = 0.9375
DllCall("msvcrt.dll", "int:cdecl", "printf", "str", "Floats: %10.3f, %10.3f", "ptr", $float1, "ptr", $float2)

ConsoleRead();

Result:

"Floats:      0.000,      0.000"

Why not use StringFormat?

Local $float1 = 0.9375
Local $float2 = 0.9375

Local $formatedText = StringFormat("Floats: %10.3f, %10.3f", $float1, $float2)
ConsoleWrite($formatedText & @CRLF)

Take a lookk on this topic to learn how to get the variable pointer and use the pointers (instead of native AutoIt variables) in your DllCall: https://www.autoitscript.com/forum/topic/180644-get-the-actual-true-pointer-for-an-autoit-native-variable-updated/

You could still use native AutoIt variables with the printf function, but using StringFormat is better and easier i think.

 

Local $float1 = 0.9375
Local $float2 = 0.9375
Local $string = "Hello" & @CRLF

Local $formatedText = StringFormat("Native: %10.3f, %10.3f", $float1, $float2)
ConsoleWrite($formatedText & @CRLF)

DllCall("msvcrt.dll", "int:cdecl", "printf", "str", "Printf: %10.3lf, %10.3f - %s", "double", $float1, "double", $float2, "str", $string)

ConsoleRead();
