Detailed Description

This class generates composite numbers.

Intended use:

Public interface

Synopsis

This class generates a list of composite numbers made up of powers of 2, 3, and 5, which are less than some max value and returns the smallest composite number greater than some number given.

Example

    CompositeNumber cn(1000);
    Int n = cn.nextLarger(319);
    Int m = cn.nextSmaller(462);
    Int l = cn.nearest(462);
