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

multiply(double multiplicand)
Returns a Score whose value is (this * multiplicand).
|
HardSoftBigDecimalScore |
negate()
Returns a Score whose value is (- this).

parseScore(String scoreString) |
HardSoftBigDecimalScore |
power(double exponent)
Returns a Score whose value is (this ^ exponent).
|

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

ScoreMath.floor(double).
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.
multiply in interface Score<HardSoftBigDecimalScore>multiplicand - value to be multiplied by this Score.public HardSoftBigDecimalScore divide(double divisor)
ScoreMath.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 in interface Score<HardSoftBigDecimalScore>divisor - value by which this Score is to be dividedpublic HardSoftBigDecimalScore power(double exponent)
ScoreMath.floor(double).
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.

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}
