# operator & method Null safety

- int other

Bit-wise and operator.

Treating both `this`

and `other`

as sufficiently large two's component
integers, the result is a number with only the bits set that are set in
both `this`

and `other`

If both operands are negative, the result is negative, otherwise the result is non-negative.

## Implementation

`int operator &(int other) => value & other;`
