Detailed Description

template<bool SE, bool HDP>
class wide_int_ref_storage< SE, HDP >

wi::storage_ref can be a reference to a primitive type,
so this is the conservatively-correct setting.   

Provide the storage for a wide_int_ref.  This acts like a read-only
wide_int, with the optimization that VAL is normally a pointer to
another integer's storage, so that no array copy is needed.   

Constructor & Destructor Documentation

wide_int_ref_storage() [1/4]

template<bool SE, bool HDP>

wide_int_ref_storage< SE, HDP >::wide_int_ref_storage ( )

inline

wide_int_ref_storage() [2/4]

template<bool SE, bool HDP>

wide_int_ref_storage< SE, HDP >::wide_int_ref_storage ( const wi::storage_ref & x )

inline

Create a reference from an existing reference.   

References wi::storage_ref::storage_ref().

wide_int_ref_storage() [3/4]

template<bool SE, bool HDP>

template<typename T>

wide_int_ref_storage< SE, HDP >::wide_int_ref_storage ( const T & x )

inline

Create a reference to integer X in its natural precision.  Note
that the natural precision is host-dependent for primitive
types.   

References wi::get_precision(), scratch, wi::storage_ref::storage_ref(), and T.

wide_int_ref_storage() [4/4]

template<bool SE, bool HDP>

template<typename T>

wide_int_ref_storage< SE, HDP >::wide_int_ref_storage ( const T & x, unsigned int precision )

inline

Create a reference to integer X in precision PRECISION.
