Description: The incident that triggered a barrage of ridicule occurred in the fall of 1994, a few months after Intel had introduced its Pentium microprocessor. The furor started with an e-mail message from Thomas R. Nicely, a mathematician at Lynchburg College in Virginia, who was doing computations related to the distribution of prime numbers. Nicely pointed out that the chip gave incorrect answers to certain floating-point (decimal) division calculations. Other users quickly confirmed the problem and identified additional examples in which an error occurs.
