From Java Example Source Code

[edit] Overview - Convert between Polar and Rectangular Coordinates

This is a Java example program.

[edit] Java Source Code

• Package: example.math
• File: MainClass.java

package example.math;
 
strictfp class MainClass {
    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);
    }
}

[edit] What Result You Can Get

Run the program, you will get:

log base e = -2.198225077669803
log base 10 = -0.9546770212133425
antilog of log base e = 0.111
anitlog of log base 10 = 0.11100000000000002
