Short for Floating Point Unit, the FPU is part of a computer specifically designed to perform floating-point mathematical operations. On October 30, 1994, Professor Thomas Nicely sent an e-mail indicating that there was an issue with the Intel Pentium processors and how they perform floating point division.
All 120 MHz and higher Intel Pentium processors are not affected by this issue. However, if you would still like to test for this problem, perform the below calculation in a calculator.
962,306,957,033 / 11,010,046 = 87,402.6282027341
962,306,957,033 / 11,010,046 = 87,399.5805831329
4,195,835 / 3,145,727 = 1.33382044913624100
4,195,835 / 3,145,727 = 1.33373906890203759
When entering this formula, you should receive a returned result of 0.
