I might add that Mathematica is designed mainly for symbolic computation, whereas IEEE floating point numbers are intended for numerical computation. Those are two very different endeavors. I played with Mathematica a bit several years ago, and I know it can do numerical computation too. I wonder if it resorts to IEEE floating point numbers when it does. -- http://mail.python.org/mailman/listinfo/python-list
