Boost C++ Libraries

...one of the most highly regarded and expertly designed C++ library projects in the world. Herb Sutter and Andrei Alexandrescu, C++ Coding Standards

QVM: Quaternions, Vectors, Matrices

normalize(quat)

#include <boost/qvm/quat_operations.hpp>

namespace boost
{
    namespace qvm
    {
        //Only enabled if: is_quat<A>::value
        template <class A>
        void normalize( A & a );
    }
}

Effects:

Normalizes a.

Postcondition:

mag(a)==scalar_traits<typename quat_traits<A>::scalar_type>::value(1).

Throws:

If a's magnitude is zero, throws zero_magnitude_error.
