binary() returning a 64bit value?

[EddieBoy]

I'm trying to calculate the size of a data block then write that value to a file in binary format. But binary() isn't behaving as I would expect and seems to be returning an 8 byte value. Here's a simplified example. Any advice on why this happens would be appreciated

$Width = 0x100
$Height = 0x100
$BPP= 0x18
$Image_Data_Size =int($Width)*int($Height)*(int($BPP/8))
ConsoleWrite($Image_Data_Size & @CRLF)
ConsoleWrite(Binary($Image_Data_Size) & @CRLF)
ConsoleWrite(Binary(196608)& @CRLF)

AutoIt changes the variable type automatically to int64 if is required. Maybe AutoIt thinks so in your case.

Edit: Yes this is the cause.

That helps thanks- drove myself crazy trying to figure out what was going on

Is there something I can change in the code to stop that from happening or should I fix it with something like BinaryMid($num,1,4)?
