(equal 0 0.0) returns NIL. Is there a way to win for checking equality of
two lisp numbers, which can be fix, flo, or big?
What's wrong with (ZEROP (DIFFERENCE x y)) ? [contagious flonumification]
There's a small problem with x being a HUGE bignum and y being a flonum, such
that a flonum overflow is generated. Also, it seems like a more efficient
check, say for two huge bignums, must exist [?].
