Quoting Jaroslav Hajek <address@hidden>:
7. pretend that there always exists a real type wide enough to hold
all 64-bit integers, and use the semantics "convert both operands to
wide real, do OP, convert to intXX". On systems where this type really
exists (like the 80-bit long double on x86) it could be implemented
directly; otherwise, it would need software emulation (painfully slow
and laborious).

Just out of curiosity, but would it be possible to have a long_double type in Octave, and would such a type solve the difficulties? Having a long_double type might be nice to have anyway.


Then we definitely want to clean up Array<T> before doing that, as this is basically the same change as I went through adding teh single precision type.
