<mathematics> The lowest positive integer and the basis for counting. Multiplication by one is an identity operator and, since one is its own reciprocal, so is division by one. One is the result of dividing any non-zero number by itself. One raised to any power is one and raising to the power one is also an identity operator.

<data> The largest digit in binary, related to the value true in Boolean algebra. Digital computers typically represent one by a high voltage and zero by a low voltage.
