[1] I tested different versions of Decimal with this telco.py. With Python from the trunk (r58550), which is the last decimal.py version previous to this change: 1241.8 After changed it to keep _int as string: 869.3 (30% faster!) But still there're a lot of room for improvements. I just commited other patch from Mark, where he reordered __new__, to minimize isinstance() checks for the most used types.} After new reordering patch: 672.9 (22% faster!) :) Regards, -- .
