The code is not recent as far as I can tell. The stated purpose here: //////////////////////////////////////////////////////////////////////////////// /// NAME: convertZZ2CF /// /// DESCRIPTION: /// Routine for conversion of integers represented in NTL as Type ZZ to /// integers in Factory represented as canonicalform. /// To guarantee the correct execution of the algorithm the characteristic /// has to equal zero. /// /// INPUT: The value coefficient of type ZZ that has to be converted /// OUTPUT: The converted Factory-integer of type canonicalform //////////////////////////////////////////////////////////////////////////////// And in some case they use the quoted snippet.
