I’ve read two bytes from a binary file into $data and now need to perform a bitwise and.
But when I do
if (($data & "\x100") != 0) {
I get the error Argument “@\0” isn’t numeric in numeric ne (!=)
Am I supposed to convert $data first?
Why are you using strings for binary operations?
Use
($data & 0x100) != 0and, if necessary, convert$datato a number.
