If you want to be truly accurate, you can use gmpy.mpq (http:// gmpy.sourceforge.net/). >>> a = [0.2, 0.2, 0.2, 0.1, 0.2, 0.1] >>> b = [0.2, 0.2, 0.2, 0.2, 0.1, 0.1] >>> qa = [gmpy.mpq(int(i * 10), 10) for i in a] >>> qb = [gmpy.mpq(int(i * 10), 10) for i in b] >>> sum(qa) mpq(1) >>> sum(qb) mpq(1) >>> sum(qa) == sum(qb) True HTH, -- Miki <[EMAIL PROTECTED]> http://pythonwise.blogspot.com -- http://mail.python.org/mailman/listinfo/python-list
