Class TruncatedFloatDataSet

java.lang.Object

org.das2.qds.AbstractDataSet

org.das2.qds.buffer.BufferDataSet

org.das2.qds.buffer.TruncatedFloatDataSet

All Implemented Interfaces:

MutablePropertyDataSet, QDataSet, WritableDataSet

public class TruncatedFloatDataSet
extends BufferDataSet
implements WritableDataSet

Truncated floats are two-byte floats with low precision used by the plasma wave group. They have an exponent the same size as a 4-byte float, but the mantissa has just 7(?) bits.
