Javascript (standard) internally uses doubleprecision floating points 
to represent it's numbers so to some extent it's possible to represent 
that numbers, although arithmetic would behave
strange in that ranges :-)

JS  is only a subset of my usecase - I want to store such values in a 
text representation  as a backup format for our
database server, and do not want to use a string representation.
I'll send you a patch against current trunk when ready, so you can have 
a look.
