operator % method

U64 operator %(
  1. U64 other
)
override

Euclidean modulo of this number by other.

Returns the remainder of the Euclidean division. The Euclidean division of two integers a and b yields two integers q and r such that a == b * q + r and 0 <= r < b.abs().

The Euclidean division is only defined for integers, but can be easily extended to work with doubles. In that case, q is still an integer, but r may have a non-integer value that still satisfies 0 <= r < |b|.

The sign of the returned value r is always positive.

See remainder for the remainder of the truncating division.

The result is an int, as described by int.%, if both this number and other are integers, otherwise the result is a double.

Example:

print(5 % 3); // 2
print(-5 % 3); // 1
print(5 % -3); // 2
print(-5 % -3); // 1

Implementation

U64 operator %(U64 other) {
  if (other.value == 0) throw UnsupportedError('Modulo by zero');
  final bi1 = BigInt.from(value).toUnsigned(64);
  final bi2 = BigInt.from(other.value).toUnsigned(64);
  return U64((bi1 % bi2).toInt().toUnsigned(64));
}
