modulo operator

   <mathematics> (mod) The operator that returns the remainder
   after integer division of its first argument by its second.
   Written as "%" in {C} and some other languages.

   Where the second argument is a power of two, the result can be
   calculated much more quickly using {bitwise and} with the
   appropriate {bit-mask}.
