Not on DEC Ada (or Compaq Ada, whatever it's called).

But, that's what I meant by "(defined large enough to hold
the all the possible numbers)".  Re-reading it I can see
that it's unclear.  I tend to be terse, but I meant the
size of the integer (8, 16, 32, etc.) has to be big enough
for the values used in the underlying representation.  And
yes they have to be the same size (for portability).  I
was taking that as a given (or implied), but thanks for
making it clearer.

For an unchecked conversion to work, the sizes have to match
exactly!
