| /** |
| * @assertion bool operator ==(Object other) |
| * Test whether this value is numerically equal to other. |
| * |
| * If both operands are doubles, they are equal if they have the same |
| * representation, except that: |
| * |
| * - zero and minus zero (0.0 and -0.0) are considered equal. They both have the |
| * numerical value zero. |
| * - NaN is not equal to anything, including NaN. If either operand is NaN, |
| * the result is always false. |
| * If one operand is a double and the other is an int, they are equal if the |
| * double has an integer value (finite with no fractional part) and |
| * identical(doubleValue.toInt(), intValue) is true. |
| * |
| * If both operands are integers, they are equal if they have the same value. |
| * |
| * Returns false if other is not a num. |
| * |
| * Notice that the behavior for NaN is non-reflexive. This means that equality |
| * of double values is not a proper equality relation, as is otherwise required |
| * of operator==. Using NaN in, e.g., a HashSet will fail to work. The behavior |
| * is the standard IEEE-754 equality of doubles. |
| * |
| * If you can avoid NaN values, the remaining doubles do have a proper equality |
| * relation, and can be used safely. |
| * |
| * Use compareTo for a comparison that distinguishes zero and minus zero, and |
| * that considers NaN values as equal. |
| * @description Check that integer values are equal if they have the same value |
