public class SmartFloatCompressed8Serializer
extends AbstractSmartFloatSerializer

A float compressed lossily into a single byte using an IEEE-754 8-bit floating point representation with 1 sign bit, 5 exponent bits and 2 significand bits (plus a hidden bit). There is no representation for NaNs or infinities - the largest values are +/-458752.0f.
