# Namespace JXG.C

↳ JXG.C

Namespace for the complex number arithmetic functions, see also JXG.Complex.
Defined in: complex.js.

Namespace Summary
Constructor Attributes | Constructor Name and Description
--- | ---
| JXG.C JXG.C is the complex number (name)space.

Method Summary
Method Attributes | Method Name and Description
--- | ---
<static> | JXG.C.abs(z1) Absolute value of a complex number.
<static> | JXG.C.add(z1, z2) Add two (complex) numbers z1 and z2 and return the result as a (complex) number.
<static> | JXG.C.conj(z1) Conjugate a complex number and return the result.
<static> | JXG.C.copy(z) Create copy of complex number.
<static> | JXG.C.div(z1, z2) Divide two (complex) numbers z1 and z2 and return the result as a (complex) number.
<static> | JXG.C.mult(z1, z2) Multiply two (complex) numbers z1 and z2 and return the result as a (complex) number.
<static> | JXG.C.sub(z1, z2) Subtract two (complex) numbers z1 and z2 and return the result as a (complex) number.

Namespace Detail
JXG.C
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);

See:
  JXG.Complex
