jcomplex

This project is a Java library for Complex Numbers. The Complex class is a modified version of the one in the project common-math developed by Apache Software Foundation.

This is a super lightweight project that provides support for complex numbers in Java.

Unlike the original Apache project, the Complex class in this library inherits from java.lang.Number.

How can I get the library?

You can download source and binaries from the release page.

Alternatively you can pull it from the central Maven repositories:

<dependency>
  <groupId>com.github.vmicelli</groupId>
  <artifactId>jcomplex</artifactId>
  <version>1.0</version>
</dependency>

How to use

To use the library just create complex number instances and call the class methods.

// import complex number class
import com.vm.jcomplex.Complex;

...

// create number 12 + 13i
Complex number = new Complex(12, 13);

// create number for polar coordinates (modulus: 10, phase: Math.PI)
Complex numberFromPolar = Complex.fromPolar(10, Math.PI);

// sum the numbers
Complex sum = number.add(numberFromPolar);

The class provides many functions such as add, multiply, subtract, divide, sin, cos, tan, asin, acos, atan, exp, log, pow and others. Operations methods return a new instance with the result.
