MachineIntegerQ

MachineIntegerQ[expr]
returns True if expr corresponds to a machine-sized integer, and False otherwise.
  • On a typical computer, system machine-sized integers must lie in the range -2^(31)+1 to +2^(31)-1 or -2^(63)+1 to +2^(63)-1.
  • Results from Mathematica are not affected by whether an integer is machine-sized or not; the speed of operations may, however, be affected.
