this to a NOTE: because pari/gp results start to get rounded incorrectly
after 192 bits of precision. APInt and pari/gp never differ by more than
1, but APInt is more accurate because it does not lose precision after 192
bits as does pari/gp.

future changes in casting. It should now be possible to improve vector
casting to deal with un-equal fp/int sizes.
