:Maybe you're too much into analytic geometry. If you replace the 1
:with any constant value, his first definition is exact. Not quite
:suitable for any computer algorithm, true, but still
:mathematically/geometrically exact.

If I say the area of a square is 1, is that the definition of the area of a
square?  Or just the
definition of 1 of infinitely many different squares?  He defined 1
ellipse, not all ellipses (or
is it ellipsi?).  And actually, even replacing it with a constant is not
exact since there are
no exact measures in our world... but don't get me started.
