Detailed Description

template<class JFirst_t, class JSecond_t = JNullType>
struct JMATH::JMath< JFirst_t, JSecond_t >

Auxiliary base class for aritmetic operations of derived class types.

Specialisation of JMath for two data types.

This class provides for the object multiplication operators *= *. The template parameter should then have the member method:

      JFirst_t& mul(const JFirst_t&, const JSecond_t&);

where JFirst_t and JSecond_t refer to the first and second template parameter, respectively.

This class uses in-class friend operators (see Barton-Nackman trick).
