public class FloatTime extends AbstractFloatScalarAbs<TimeUnit,FloatTime,DurationUnit,FloatDuration>
FloatScalar.Abs<TimeUnit> value = new FloatScalar.Abs<TimeUnit>(100.0, TimeUnit.SI);we can now write:
FloatTime value = new FloatTime(100.0, TimeUnit.SI);The compiler will automatically recognize which units belong to which quantity, and whether the quantity type and the unit used are compatible.
Note that when the offset of a stored absolute Time becomes large, precision of a float might not be enough for the required resolution of a Time. A float has around 7 significant digits (23 bit mantissa). This means that when we need to have a float time that is precise to microseconds, the Time value should not go above 2^22 = 4.0E6. This is not enough to store Epoch values that are in the order of magnitude of 2E12 ms! So feeding System.TimeInMillis() to a FloatTime with TimeUnit.BASE as its unit is not having the required precision. At best, a FloatTime can store TimeUnit.BASE or TimeUnit.EPOCH values with real calendar values with a precision of several minutes.
