public class FloatSet

extends SimpleSet

FloatSet represents the finite (but large) set of samples of R^dimension made by vectors of IEEE single precision floating point numbers. FloatSet objects are immutable.

FloatSet cannot be used for the domain sampling of a Field.

Constructor Summary

FloatSet(MathType type)
construct a FloatSet object with null CoordinateSystem and Units

FloatSet(MathType type, CoordinateSystem coord_sys, Unit[] units)
the set of values representable by N floats; type must be a RealType, a RealTupleType or a SetType; coordinate_system and units must be compatible with defaults for type, or may be null; a FloatSet may not be used as a Field domain
