This advice would probably only cause more confusion, because we are now
moving into the direction that character strings are no longer acceptable
as numeric data.
Note that
x <> 0
is also a perfectly good way to convert integers to booleans, and a more
portable one at that.
Finally, you can always create your own cast.
