ComplexD class public functions

---

ComplexD(void);

Creates a complex number with the real and imaginary parts undefined.

ComplexD(double realPart, double imagPart = 0);

Creates a complex number from a real number, or a real and imaginary part of a complex number.

ComplexD(const ComplexD& aNumber);

Creates a complex number from another complex number.

~ComplexD();

Does nothing.

double abs(void) const;

Returns the absolute value of the complex number.

double arg(void) const;

Returns the argument (angle) of the complex number in radians.

ComplexD cexp(double aPower = 1);

Returns the complex exponential E^(this*aPower).

ComplexD conj(void) const;

double& im(void);

Returns the imaginary part of the complex number.

double& operator[](int index);

this[0] returns the real part of the complex number; this[1] returns the imaginary part of the complex number.
