Detailed Description
template<class numType>
class unifexp::mapQuadr< numType >
This class defines the quadratic map f(x)=x^2-a without using interval arithmetic.
It is suitable for non-rigorous computations. See the class "mapQuadrIntv" for a rigorous version which does use interval arithmetic. Valid values of the parameter are between 1+ and 2 (optimal value: 2).
