Re: xor in PL/SQL

Hi,

thank you all for your more or less helpful posts. I know how to implement xor myself, but I wanted to know if I have overseen something about xor in the documentation. Xor is implemented in most CPUs. I don't understand why I should write code (that will take a lot longer to execute) for an operation that is already there as hardware.
