  <para>Example:</para>

  <programlisting>Rad2Deg := 57.295779513082; //number of degrees in a radian

Deg2Rad := 0.0174532925199; //number of radians in a degree

Angle45 := 45 * Deg2Rad;    //translate 45 degrees into radians

HyperbolicCosine45 := COSH(Angle45);
                            //get hyperbolic cosine of the 45 degree angle
