# operator & method Null safety

BigInt operator & (

1. BigInt 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`

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

## Implementation

    BigInt operator &(BigInt other);
