The documentation for Math::BigInt says, regarding $e, the output from
exponent():
Currently, for BigInts $e is always 0, except for NaN, +inf and -inf,
where it is "NaN"; [...]
The correct is
Currently, for BigInts $e is always 0, except +inf and -inf, where it
is "+inf"; and for NaN, where it is "NaN"; [...]
Patch attached.

C<< ($m,$e) = $x->parts() >> is just a shortcut that gives you both of them
in one go. Both the returned mantissa and exponent have a sign.
