one
1

    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.

    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.
