BitAnd

BitAnd[n1,n2,]

gives the bitwise AND of the integers ni.

Details

  • Integer mathematical function, suitable for both symbolic and numerical manipulation.
  • BitAnd[n1,n2,] yields the integer whose binary bit representation has ones at positions where the binary bit representations of all of the ni have ones.
  • For negative integers BitAnd assumes a two's complement representation.
  • BitAnd automatically threads over lists.
