Re^2: Boolean counter?

in reply to Re: Boolean counter?
in thread Boolean counter?

I agree that the XOR solution is perfectly correct, but why use that instead of NOT? Isn't

 $counter = ! $counter;

easier to read? That said, I have to admit that I like the snazzyness of the in place ^= syntax. It is hard to get more concise than that.

The difference is that $toggle ^= 1; leaves you with a number (0 or 1) while $toggle = !$toggle; leaves you with a boolean.

Honestly, it sounds like the OP wants a boolean, so the easier to read negation should be used. If he wants to display the boolean, that's an outputting formatting issue to be resolved then.
