\begin{ccRefFunction}{to_interval}

\ccDefinition

The template function \ccRefName\ computes for a given real embeddable 
number $x$ a double interval containing $x$. 
This interval is represented by a \ccc{std::pair<double,double>}. 
The function is defined if the argument type 
is a model of the \ccc{RealEmbeddable} concept.
