One of the most famous expressions used in the average kindergarten classroom made a bit more confusing by Intel. Seeing as computers never make mathmatical errors, I guess 1+1=1.99999999486 after all.

In the early days of the 8086 architecture, in order to make certain routines as efficient as possible, Intel programmed a pretty good Floating Point Number (FPN) addition routine. Unfortunately, they didn't test the chip out properly and found that the processor understood FPN 1 plus FPN 1 equals FPN 1.9999999486. This ovbiously sucked, and since the 8086, Intel has corrected the error and made it more efficient.
