Don't forget ``num % 2 == 0``.
None should matter, pretty much all production compilers within the
last 30 years should recognize all forms of this and do the right thing.
Thanks. Fastest reply ever! And I believe across the world? I suppose
my examples required overhead of a function call. So maybe num % 2 == 0
is fastest?
Indeed, all the way from New Zealand.
I wouldn't bother timing this. A compiler will rewrite it and emit
whatever instructions it thinks is best for a given cpu target that you
select. This is one of those things that was solved 30 years ago :)
