Method Detail
-
get
public static BinaryScaleFactor get(int powerOf2)
-
getFloor2Factor
public static BinaryScaleFactor getFloor2Factor(long value)
-
getFloor1024Factor
public static BinaryScaleFactor getFloor1024Factor(double value)
-
getMultiplier
public double getMultiplier()
- Returns:
- the multiplier which source values should be multiplied with (before the
offset
is added)
-
asExponentialStringBuilder
public StringBuilder asExponentialStringBuilder(boolean multiplicationSign)
-
targetOutOfRange
public boolean targetOutOfRange(long srcNumericalValue, long maxAbsValue)
-
targetOutOfRange
public boolean targetOutOfRange(double srcNumericalValue, long maxAbsValue)
-
targetValue
public long targetValue(long srcNumericalValue)
- Parameters:
srcNumericalValue
- a numerical quantity value, expressed in the source unit- Returns:
- the corresponding numerical quantity value, when expressed in the target unit,
rounded to the closest integer that can be represented by a
long
-
targetFloor
public long targetFloor(long srcNumericalValue)
- Parameters:
srcNumericalValue
- a numerical quantity value, expressed in the source unit- Returns:
- the floor of the corresponding numerical quantity value, when expressed in the target
unit, clamped to a
long
-
targetValue
public double targetValue(double srcNumericalValue)
- Parameters:
srcNumericalValue
- a numerical quantity value, expressed in the source unit- Returns:
- the corresponding numerical quantity value, when expressed in the target unit
-
isUnity
public boolean isUnity()
- Returns:
- true iff this represents the identity transform
-
isInteger
public boolean isInteger()
- Returns:
- true iff this transform can exactly be described by an integer multiplier followed by an integer offset
-
