# 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.

## Generalizations & Extensions(1)

Basic symbolic simplifications are done automatically:

## Applications(5)

Extract the second-lowest-order bits in numbers:

"Mask" to test whether bits 3 or 4 are 1:
