Hi, In [2]: sum([.1, .1, .1, .1, .1, .1, .1, .1, .1, .1]) Out[2]: 0.9999999999999999
In ipython, I got the above output. But I got a different output from "print". Is there a way to print exact what I saw in ipython? ~/linux/test/python/man/library/math/fsum$ cat main.py #!/usr/bin/env python print sum([.1, .1, .1, .1, .1, .1, .1, .1, .1, .1]) ~/linux/test/python/man/library/math/fsum$ ./main.py 1.0 Regards, Peng -- http://mail.python.org/mailman/listinfo/python-list
