I think that the previous poster was asking something different. I think he was asking something like this: If >>> t1 = 0.500 >>> t2 = 0.461 >>> print t1-t2 0.039 Then why: >>> t1 += 12345678910 >>> t2 += 12345678910 >>> # Note, both t1 and t2 have been incremented by the same amount. >>> print t1-t2 0.0389995574951 It appears Yu-Xi Lim beat me to the punch. Using decimal as opposed to float sorts out this error as floats are not built to handle the size of number used here. Ben -- http://mail.python.org/mailman/listinfo/python-list
