Namespace

JXG.Math.C namespace for the complex number arithmetic functions, see also JXG.Complex.

JXG.C is the complex number (name)space. It provides functions to calculate with complex numbers (defined in JXG.Complex). With this namespace you don't have to modify your existing complex numbers, e.g. to add two complex numbers:

  var z1 = new JXG.Complex(1, 0);
  var z2 = new JXG.Complex(0, 1);
  z = JXG.C.add(z1, z1);

z1 and z2 here remain unmodified. With the object oriented approach above this section the code would look like:

  var z1 = new JXG.Complex(1, 0);
  var z2 = new JXG.Complex(0, 1);
  var z = new JXG.Complex(z1);
  z.add(z2);
