| 16:43 | When SQLITE_OMIT_FLOATING_POINT is defined, the floating-point formats in the sqlite3_*printf() functions should pull an int64 off of the parameter list and ignore it. check-in: 3fd6f9ad user: drh tags: trunk | |
| 16:25 | When SQLITE_OMIT_FLOATING_POINT is defined, make sure the result of a mathematical operation is always tagged as an integer. check-in: e12da0d3 user: drh tags: trunk | |
