an integer having a range at leaast large enough to hold the values
-32767..32767
(I may be off a bit on the values but it translates to 16 bits or
larger)

whilst this degree of abstraction is often good the ability to fiddle
with representaion is also sometimes useful. And if we want our
programs to terminate before the sun goes cold knowing about
representaion is sometimes useful.

I accept many langaues don't reveal represetnation details to the
degree that C (and C++) does.
