Constructor Detail

KlvIntegerEncodedFloatingPoint

public KlvIntegerEncodedFloatingPoint(KlvNumericalDataElement<?> klvRawDataValue,
                                      long encodedRangeMin,
                                      long encodedRangeMax,
                                      double actualRangeMin,
                                      double actualRangeMax)

Constructs a KlvIntegerEncodedFloatingPoint representing a KLV element containing a floating-point value that has been encoded as an integer value.

The value returned by this KlvIntegerEncodedFloatingPoint is calculated as follows:

The value returned by klvRawDataValue is converted to a long Scale the value by calculating: (value - encodedRangeMin) / (encodedRangeMax - encodedRangeMin) Apply the scaled value to the actual range: scaled value * (actualRangeMax - actualRangeMin) + actualRangeMin

Parameters:

klvRawDataValue - the KlvNumericalDataElement that retrieves the raw numerical value

encodedRangeMin - the minimum integer-encoded value

encodedRangeMax - the maximum integer-encoded value

actualRangeMin - the minimum decoded floating-point value

actualRangeMax - the maximum decoded floating-point value
