It is not at all certain that your CPU is always counting correctly

On a daily basis, one can assume that when you ask a computer – whether it is a PC, server, smartphone or something else with a relatively powerful processor – to perform a calculation, it returns the correct answer. The processor suppliers have extensive experience in testing and weeding out any errors of this type, so it is one of the rarities that design errors are detected in CPUs that result in the processor calculating errors.
