Class HashedRangedToNonuniformDouble

java.lang.Object

io.virtdata.basicsmappers.from_long.to_double.HashedRangedToNonuniformDouble

All Implemented Interfaces:

DataMapper<Double>

public class HashedRangedToNonuniformDouble
extends Object
implements DataMapper<Double>

This provides a random sample of a double in a range, without accounting for the non-uniform distribution of IEEE double representation. This means that values closer to high-precision areas of the IEEE spec will be weighted higher in the output. However, NaN and positive and negative infinity are filtered out via oversampling. Results are still stable for a given input value.
