NOTE: ClearContent should make leading coeff. positive! NOTE: testing alg. and trans. extensions of Q aswell as Q itself add: Added testing of Clear* to 'make check'

8:16 PM Changeset in git [dc79bd]jengelh-datetimespielwiese by Oleksandr Motsak <motsak@…>
Major Update for Enumerators + Fixes for Algrbraic & Transcendental extensions General: chg: cleanup + documentation + additional assumes Enumerators: chg: some polish on Enumerators add: CRecursivePolyCoeffsEnumerator<ConverterPolicy> for recursive treatment of converted coeffs as Enumerators Coeffs: chg: use mpz_lcm for readability in nlClearDenominators + cleanup add: nlClear*NoPositiveLead variants should not make LC positive chg: all nlClear* are not static in order to be usable from alg / trans exts. fix: fixed a bug in ndClearContent AlgExt: add: nCoeff_is_Q_algext for checking an alg. ext. of Q add: naClear* for alg. ext. over Q NOTE: coeffs are polynomials in Q[a] - one should simply consider each of them recursively as a collection of numbers... NOTE: compute GCDs over Alg. Ext... + gcds of (int.) numbers!? NOTE: trying to be conform with older Singular: no negative leading coeff. normalization chg: Alg. Ext: use singclap_*gcd (instead of Frank's gcd-stuff) p_poly: add: p_Cleardenom_n/p_Cleardenom also clear content afterwards... chg: major and minor changes to p_Content/p_Cleardenom_n/p_Cleardenom + cleanup add: additionally trying to assure positive leading coeff. after p_Content/p_Cleardenom_n(/p_Cleardenom?) NOTE: which should not be needed as n_ClearDenominators/n_ClearContent are supposed to assure that themselves! add: more assumes to p_polys.cc NOTE: massive usage of enumerators form p_* causes problems - only doing that for Q_a()! NOTE: do -normalization over Q(x...) TransExt: add: ntClear* for trans. ext's fix: correct ntGetDenom/ntGetNumerator (thanks to pSubstPar), NOTE: no negative denominator out of ntGetNumerator/ntGetDenom! add: first inefficient ntClearContent/Q and ntClearDenominators/Q & F_p impl. NOTE: careful with the use of nlClear* ! (only over Q!) add: added ntTest to transext.cc on most in/outs + use ntInit(poly)! NOTE: trying to fix the monic-poly-gcd problem in ntClearDenominators!
8:15 PM Changeset in git [095dee7]jengelh-datetimespielwiese by Oleksandr Motsak <motsak@…>

Preparing the removal of Frank's p_Monic/p_Gcd/p_ExtGcd from common use chg: moved most of the functions (with helpers) into algext.cc and made them static NOTE: p_PolyDiv stayed in p_polys.cc as it is used in convFactoryASingA NOTE: p_ExtGcd also is made public via algext.h (needed elsewhere?)
