14:01 | Add the geopoly_regular(X,Y,R,N) function to the geopoly extension. (check-in: 4505bbae58 user: drh tags: trunk) | |
13:18 | Make most geopoly functions pure. (check-in: 944e167a98 user: drh tags: trunk) | |
00:16 | Rig geopoly to use sqlite3AtoF() if it is available, as that routine is much faster than atof(). (check-in: 470c6c07d0 user: drh tags: trunk) | |
