FromDoubleConstructible Concept Reference

## Definition

A model of the concept `FromDoubleConstructible` is required to be constructible from the type `double`.

In case the type is a model of `RealEmbeddable` too, for any double d the identity: `d == CGAL::to_double(T(d))`, is guaranteed.

## Creation
| FromDoubleConstructible (const double &d)
| conversion constructor from double.
