using System;
using Imsl.Finance;

public class fvscheduleEx1
{
    public static void  Main(String[] args)
    {
        double principal = 10000.0;
        double[] schedule = new double[]{.050, .051, .052, .053, .054};
        double fvschedule;
        
        fvschedule = Finance.Fvschedule(principal, schedule);
        Console.Out.WriteLine("After 5 years the $10,000 investment " +
                              "will have " + "grown to " + 
                              fvschedule.ToString("C"));
    }
}
