operator & method

int? operator &(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) {
  if (value != null) {
    return value! & other;
  }
  return null;
}
