Class SingleDocValuesField

Syntactic sugar for encoding floats as NumericDocValues via SingleToRawInt32Bits(float).

Per-document floating point values can be retrieved via GetSingles(AtomicReader, string, bool).

NOTE: In most all cases this will be rather inefficient, requiring four bytes per document. Consider encoding floating point values yourself with only as much precision as you require.

NOTE: This was FloatDocValuesField in Lucene
