Class Numeric

  • All Implemented Interfaces:
    Number<Real>, java.io.Serializable, java.lang.Comparable<Real>, org.apache.commons.math3.FieldElement<Real>

    public final class Numeric
extends Real
implements java.io.Serializable
    Implementation of floating point numbers based on Java double.

    This class implements all mathematical operations declared in Number as operations with doubles. So all methods return numeric numbers. As for example, 1.0 + 2 / 3 will give 1.666666 and so on. All mathematical methods works with its arguments using Number.doubleValue() method.
