public final class HardSoftLongScore extends AbstractScore<HardSoftLongScore> implements FeasibilityScore<HardSoftLongScore>
Score
is based on 2 levels of long constraints: hard and soft.
Hard constraints have priority over soft constraints.
This class is immutable.

In a normal score comparison, the soft score is irrelevant if the 2 scores don't have the same hard score.

.
If the implementation has a scale/precision, then the unspecified scale/precision of the double multiplicand should have no impact on the returned scale/precision.

multiplicand
- value to be multiplied by this Score.public HardSoftLongScore divide(double divisor)
Score
Math.floor(double)
.
If the implementation has a scale/precision, then the unspecified scale/precision of the double divisor should have no impact on the returned scale/precision.
divide

divisor
- value by which this Score is to be dividedpublic HardSoftLongScore power(double exponent)
Score

If the implementation has a scale/precision, then the unspecified scale/precision of the double exponent should have no impact on the returned scale/precision.

Score
When rounding is needed, each rounding should be floored (as defined by Math.floor(double)
.
The length of the returned array must be stable for a specific Score
implementation.
For example: -0hard/-7soft
returns new int{-0, -7}
