Class FloatBoundedQuantization

java.lang.Object

eu.bandm.sig.adlib.FloatBoundedQuantization

public class FloatBoundedQuantization
extends Object

Canonical near-invertible maps between a float interval of the form [a; b] and an integer interval of the form [0, n].

This class is particularly useful to bind signals to GUI components.
