Detailed Description

template<typename C>
class lass::num::interval< C >

Interval class.

Class for interval arithmetic. The arithmetic is weak interval arithmetic: there is no rounding code, to speed up things. It should however be useful except for numerical stability studies on the bitlevel. If you wont strong interval arithmetic, look for the boost library.

Warning
DO NOT derive a class from this one which uses dynamic memory management! destructor is not virtual. This is to avoid the functionptrtable to be stored in the objects. Therefor none of the methods are virtual
