op - Operation #




A Dart library defining interfaces for mathematical operations, such as addition and multiplication
Usage #
See example/main.dart
Addable
void main() {
final Integer summand1 = Integer(6);
print(summand1); // 6

final Integer summand2 = Integer(5);
print(summand2); // 5

final Integer sum = summand1 + summand2;
print(sum); // 11
}

class Integer implements Addable<Integer, Integer> {
Integer(this.value);

final int value;

@override
Integer operator +(Integer y) => Integer(value + y.value);

@override
String toString() => value.toString();
}

Multipliable
void main() {
final RealNumber multiplicand = RealNumber(4);
print(multiplicand); // 4

final RealNumber multiplier = RealNumber(7);
print(multiplier); // 7

final RealNumber product = multiplicand * multiplier;
print(product); // 28
}

class RealNumber implements Multipliable<RealNumber, RealNumber> {
RealNumber(this.value);

final num value;

@override
RealNumber operator *(RealNumber y) => RealNumber(value * y.value);

@override
String toString() => value.toString();
