\begin{ccRefFunction}{gcd}

\ccDefinition

The function \ccRefName\ computes the greatest common divisor of two values.

In case the argument types \ccc{NT1} and \ccc{NT2} differ, 
the \ccc{result_type} is determined via \ccc{Coercion_traits}.\\
Thus, the \ccc{result_type} is well defined if \ccc{NT1} and \ccc{NT2} 
are a model of \ccc{ExplicitInteroperable}. \\
The actual \ccRefName\ is performed with the semantic of that type.

The function is defined if \ccc{result_type}
is a model of the \ccc{UniqueFactorizationDomain} concept.

\ccFunction{template <class NT1, class NT2> result_type 
            gcd(const NT1& x, const NT2& y);}{}
