Intel’s FPU was built into the processing chip which did increase its computing speed, but it had errors on its instructions for division. When brought to Intel’s attention by math professor Thomas Nicely, Intel’s response was non chalant. Someone took his phone call, did the calculations with him & proved Mr. Nicely correct
