Detailed Description

This template class is define just to be in phase with the LinBox archetype. Most of all methods are inherited from Montgomery<Std32> class of Givaro. this class is a modular representation with a Montgomery reduction

Constructor & Destructor Documentation

GivaroMontg (  const integer &    p )  [inline]

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

Member Function Documentation

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

long characteristic (    )  const [inline]

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.

double& convert (  double &    x, const Element &    y )  const [inline]

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: x  integer to contain output (reference returned). y  constant field base element.

int getMaxModulus (    )  [inline, static]

Element& init (  Element &    x, const double    y = 0.0 )  const [inline]

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: x  field base Element to contain output (reference returned). y  integer.
