Unum is a number representation system that is a superset of IEEE integers 
and IEEE floats which avoids many problems (especially in floating point 
arithmetic) as it has no rounding, no overflow to infinity, no underflow to 
zero, and is safe to parallelize.

I was wondering if anyone has implemented or is interested in implementing 
this in Clojure/ClojureScript (or Java/JavaScript)?

There is an existing reference implementation written in Mathematica and it 
appears a port has already been done to Python:
