Usage

From source file:syncleus.dann.math.ComplexNumber.java

@Override
public final ComplexNumber tanh() {
    final double denominator = Math.cosh(2.0 * getReal()) + Math.cos(2.0 * getImaginary());
    return new ComplexNumber(Math.sinh(2.0 * getReal()) / denominator,
            Math.sin(2.0 * getImaginary()) / denominator);
}
