How to differentiate two constructors with the same parameters?

Suppose we want two constructors for a class representing complex numbers:

Complex (double re, double img) // construct from cartesian coordinates
Complex (double A, double w) // construct from polar coordinates

but the parameters (number and type) are the same: what is the more elegant way
to identify what is intended? Adding a third parameter to one of the constructors?


It is better to add static methods with appropriate names and let them to create the objects.

static Complex createFromCartesian(double re, double img);
static Complex createFromPolar(double A, double w);
