Because computers _don't_do_math_. That is a very important thing to remember. Computer do something that _approximates_ math... in some situations... if you know what you're doing. In you're case you're doing IEEE floating point operations. Before you use floating point, you should read the article by Goldman that has been suggested: https://docs.oracle.com/cd/E19957-01/806-3568/ncg_goldberg.html https://dl.acm.org/doi/10.1145/103162.103163 -- Grant -- https://mail.python.org/mailman/listinfo/python-list
