BitAnd

BitAnd[n₁, n₂, ...]
gives the bitwise AND of the integers n_i.

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 n_i have ones.

Use numbers of any size:

BitAnd takes any number of arguments:

Use negative numbers:

Basic symbolic simplifications are done automatically:

Extract the second-lowest-order bits in numbers:

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

Make a nested pattern:

Test for powers of 2:
