In terms of documenting code,
(n % 2 == 1)
is *much* less satisfactory than
(n.even?)
And in any case, sometimes the first equation could mean different things (even though the result is identical). For instance:
(n.valve_open?)
could have the same meaning if the last bit is being tested for being one or zero. If you use the first equation, none of this can be seen in the code.
However, matz's point comes into its own here: why not use
def even?
n % 2 == 1
end
?? The only thing gained otherwise would be machine optimization.

Hi,
Finally, I got access to comp.lang.ruby.

Both
n % 2 == 1
(n ^ 1) == 1
would work. Do we really need it?
If I have to add odd?, I'd add even? too.
