I updated the file, if you view it, use courier new size 10 and it should line up nicely.
I still haven't been able to assign 18,446,744,073,709,551,615 to a variable yet.
quad q = 18446744073709551615
print str( q )
extended e = 18446744073709551615
print str( e )
'both cases I get: -9.2233720368547758E+18
