Detailed Description

wrapper of Givaro's Montgomery<Std32>.

This class is a modular representation with a Montgomery reduction


Member Typedef Documentation

typedef Montgomery<Std32>::Rep Element

Element type. This type is inherited from the Givaro class Montgomery<Std32>

typedef GIV_randIter< Montgomery<Std32>, LinBox::integer > RandIter

RandIter type This type is inherited from the Givaro class Montgomery<Std32>


Constructor & Destructor Documentation

GivaroMontg ( const integer p) [inline]

Constructor from an integer this constructor use the ZpzDom<TAG> constructor

GivaroMontg ( const integer p,
const integer k 
) [inline]

Constructor from an integer (takes degree of extension as 2nd parameter, must be 1) this constructor use the ZpzDom<TAG> constructor


Member Function Documentation

integer& characteristic ( integer c) const [inline]

Characteristic. Return integer representing characteristic of the domain. Returns a positive integer to all domains with finite characteristic, and returns 0 to signify a domain of infinite characteristic.

Returns:
integer representing characteristic of the domain.
integer& cardinality ( integer c) const [inline]

Cardinality. Return integer representing cardinality of the domain. Returns a non-negative integer for all domains with finite cardinality, and returns -1 to signify a domain of infinite cardinality.

Returns:
integer representing cardinality of the domain
Element& init ( Element x,
const integer y = 0 
) const [inline]

Initialization of field base Element from an integer. Behaves like C++ allocator construct. This function assumes the output field base Element x has already been constructed, but that it is not already initialized. We assume that the type of Element is short int. this methos is just a simple cast.

Returns:
reference to field base Element.
Parameters:
xfield base Element to contain output (reference returned).
yinteger.
integer& convert ( integer x,
const Element y 
) const [inline]

Conversion of field base element to an integer. This function assumes the output field base element x has already been constructed, but that it is not already initialized.

Returns:
reference to an integer.
Parameters:
xinteger to contain output (reference returned).
yconstant field base element.
