BitOr[n1,n2,…]
gives the bitwise OR of the integers ni.
Details

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