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.
