Conversion between polar and rectangular coordinates

[Java Tip]

import java.lang.*;

strictfp class Logs
{
public static void main(String[] args)
{
     double num, loge, log10, aloge, alog10;

     // Obtain input from user
     num = 0.111d;

     // Calculate and display the natural logarithm
     loge = Math.log(num);
     System.out.println("log base e = " + loge);
     // Calculate the common log
     log10 = Math.log(num)/Math.log(10.0);
     System.out.println("log base 10 = " + log10);

     // Calculate the antilogarithm of log base e
     aloge = Math.exp(loge);
     System.out.println("antilog of log base e = " + aloge);

     // Calculate the antilogarithm of log base 10
     alog10 = Math.pow(10.0, log10);
     System.out.println("anitlog of log base 10 = " + alog10);
