Build Identifier:

After inserting a number that is too large for a numeric table any number that is added to the column is different than the number stored.

Reproducible: Always

Steps to Reproduce:

Run the following in an mclient:

CREATE TABLE test_table4 (d NUMERIC(12,2));
INSERT INTO test_table4 VALUES (531421754532.553234531231250);
INSERT INTO test_table4 VALUES (531421754532);
INSERT INTO test_table4 VALUES (531421754);
INSERT INTO test_table4 VALUES (53142175);
INSERT INTO test_table4 VALUES (53142);
SELECT * FROM test_table4;

Actual Results:

+----------------+
| d |
+================+
| 710.43 |
| 709.88 |
| 7950.72 |
| -2894.68 |
| -2198.23 |
+----------------+

Expected Results:

+----------------+
| d |
+================+
| 531421754.00 |
| 53142175.00 |
| 53142.00 |
