In the sqlite3_value or Mem object, make the MEM_IntReal type completely independent from MEM_Int and MEM_Real. This helps avoid problems when inserting non-float values into a "REAL" column. check-in: 5a8a23ee user: drh tags: trunk
New testcase macros to ensure that MEM_IntReal is fully tested. Closed-Leaf check-in: 8b8ef445 user: drh tags: int-real
Add the SQLITE_TESTCTRL_RESULT_INTREAL test-control and use it to create the intreal() SQL function in testfixture. Write a few simple tests to prove this all works. TH3 will hold most of the INTREAL tests, probably. check-in: c9838731 user: drh tags: int-real
Improved comments on the elements of the array constant used to implement the sqlite3_value_type() interface. check-in: f73a7de7 user: drh tags: int-real
Make MEM_IntReal a completely independent type, meaning a floating point value stored as an integer. This fixes a problem with arithmetic within arguments to string functions on indexes of expressions. But it is a big change and needs lots of new testcase() macros for MC/DC and so it is initially put on this branch. check-in: dba836e3 user: drh tags: int-real
Ensure that the typeof() function always returns SQLITE_FLOAT for floating point values even when the value is stored as an integer to save space. check-in: 48889530 user: drh tags: trunk
