operator == method

@override bool operator ==(Object obj)

Returns true if this Quantity is equal to obj. Two Quantity objects are considered equal if their MKS values and dimensions are equal. Only values and dimensions are considered; other attributes such as uncertainty and preferred units are ignored.

Scalar quantities are also considered equal to num and Number objects with matching values.

Implementation

@override
bool operator ==(Object obj) {
  if (this is Scalar && (obj is num || obj is Number)) return valueSI == obj;

  if (obj is Quantity) {
    if (!(dimensions == obj.dimensions)) return false;
    return compareTo(obj) == 0;
  }
  return false;
}
