Hello,

Octave can conveniently be extended using external C++ packages. If
you'd like to contribute a multi-precision package, probably the best
way to start is to check out David Bateman's fixed point numbers
package:
http://octave.sourceforge.net/fixed/
I don't think we want multiprecision computing in Octave's core now,
but that may change in the future.
