Bug #1208 bigint precision problem

Description:
Not sure if this has been fixed in a newer version. Couldn't find reference to fix anywhere in bug system. Using MyISAM table. SQL is as follows:

mysql> select SID_HIGH from SID_COUNT where SID_HIGH = 13440289507735259807;
+----------------------+
| SID_HIGH             |
+----------------------+
| 13440289507735259807 |
| 13440289507735259136 |
+----------------------+
2 rows in set (28.42 sec)

Table structure is as follows:

mysql> describe SID_COUNT;
+--------------+---------------------+------+-----+---------------------+-------+
| Field        | Type                | Null | Key | Default             | Extra |
+--------------+---------------------+------+-----+---------------------+-------+
| SID_LOW      | bigint(20) unsigned |      | PRI | 0                   |       |
| SID_HIGH     | bigint(20) unsigned |      | PRI | 0                   |       |
| DATETIME     | datetime            |      |     | 0000-00-00 00:00:00 |       |
| PREFIX       | char(1)             |      |     |                     |       |
| COMPANY_CODE | char(3)             | YES  |     | NULL                |       |
| ZIP          | char(5)             | YES  |     | NULL                |       |
| CREATE_DATE  | datetime            | YES  |     | NULL                |       |
+--------------+---------------------+------+-----+---------------------+-------+

My understanding was that unsigned bigint was a 64-bit number so maximum value would be 18446744073709551616. So my value in query should be OK.

Also having similar (possibly related?) issues inserting bigints into table where last few digits are altered when they should be the same. Using MySQL/J JDBC driver for inserts.

How to repeat:
I can provide more help in repeating if needed. Hoping that this a known bug in the 3.23.x versions and that you can point me to documentation that talks about problem and how it was fixed in later versions.

Ok, this seems to be a bug only in the 3.23 tree:

(looks like 13440289507735259136 is the maximum value for 3.23)

We have generally stopped the development on the 3.23 tree and only critical
bugfixes will be applied - this will be left to decide by Monty, our CTO, whether
the current one qualifies as such.

But you should consider upgrading to the current stable, 4.0 tree.

This is a known issue in 3.23.

In 3.23 we used floating point for bigint calculus.

We switched to 64-bit integer calculus in 4.0, which will not be back-ported to 3.23.
