I haven't look at any of the n-d array code so I'm not sure what all 
that entails.

I was testing and wrote a few mixed type operations to deal with scalars 
and multiple precision integers so a few other mixed type operations 
wouldn't be difficult to add.

I actually only implemented the multiple precision integer portion so 
probably the best thing to do would be rewrite it so that the type is of 
either multiple precision integer or multiple precision floating point 
and determine which to use depending on the operations performed.  Ie., 
if you start with an integer and perform only addition, subtraction, and 
multiplication the result is still a multiple precision integer and will 
not be a multiple precision float.
