public final class SimpleDoubleScore extends AbstractScore<SimpleDoubleScore>
Score
is based on 1 level of double constraints.
WARNING: NOT RECOMMENDED TO USE DUE TO ROUNDING ERRORS THAT CAUSE SCORE CORRUPTION.
For example, this prints false: System.out.println((0.01 + 0.05) == (0.01 + 0.02 + 0.03));
Use SimpleBigDecimalScore
instead.
This class is immutable.

.
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 SimpleDoubleScore 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.
divisor
- value by which this Score is to be dividedpublic SimpleDoubleScore power(double exponent)
Score
Math.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.
exponent
- value by which this Score is to be poweredpublic SimpleDoubleScore negate()
Score
public Number[] toLevelNumbers()
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}
