Detailed Description

The storage used by wide_int.

Constructor & Destructor Documentation

◆ wide_int_storage() [1/3]

wide_int_storage::wide_int_storage ( )

inline

◆ wide_int_storage() [2/3]

template<typename T >

wide_int_storage::wide_int_storage ( const T & x )

inline

Initialize the storage from integer X, in its natural precision.
Note that we do not allow integers with host-dependent precision
to become wide_ints; wide_ints must always be logically independent
of the host.

Member Function Documentation

◆ create()

wide_int wide_int_storage::create ( unsigned int precision )

inlinestatic

Return an uninitialized wide_int with precision PRECISION.

◆ from()

wide_int wide_int_storage::from	(	const wide_int_ref &	x,
		unsigned int	precision,
		signop	sgn )

inlinestatic

Treat X as having signedness SGN and convert it to a PRECISION-bit
number.

◆ from_array()

wide_int wide_int_storage::from_array	(	const HOST_WIDE_INT *	val,
		unsigned int	len,
		unsigned int	precision,
		bool	need_canon_p = true )

inlinestatic

Create a wide_int from the explicit block encoding given by VAL and
LEN.  PRECISION is the precision of the integer.  NEED_CANON_P is
true if the encoding may have redundant trailing blocks.
