Revision 1.19 / (download) - annotate - [select for diffs], Thu Mar 29 01:32:52 2018 UTC (6 years, 9 months ago) by noro
Branch: MAIN
CVS Tags: HEAD

nd_{gr,f4}(B,V,P,O) accepts large prime P:
If P>=2^30 then the computation is done over a large finite field GF(P) (slow).
If P<2^30 then it is done over a small finite field GF(P) (fast).
Fixed a performance bug in modfctr().
