Detailed Description

LinBox fields, field wrappers, field construction tools.

LinBox fields implement the concept which is specified in the field archetype.

Some implement a basic ring concept rather than a field (inv and div are partial functions). Ring representations with additional functions are also found in the ring directory.

Function Documentation

NTL::ZZ_p& Givaro::Caster ( NTL::ZZ_p &  x,
const Integer &  y 

Initialization of field element from an Integer.

Behaves like C++ allocator construct. This function assumes the output field element x has already been constructed, but that it is not already initialized. This done by converting to a std::string : inefficient but correct.

reference to field element.
xfield element to contain output (reference returned).
