The documentation at

"The default value is 2GB."

In fact, as shown in the table above the text, the default value is 2Gb for 32-bit systems and 9 Eb for 64-bit systems. As the most of the systems are 64bit, 2Gb in the text is misleading.

How to repeat:
mysql> show variables like 'myisam_max_sort_file_size';
| Variable_name             | Value               |
| myisam_max_sort_file_size | 9223372036853727232 |
1 row in set (0.02 sec)

Suggested fix:
Include both values or remove default from the text while keeping in the table.

Thank you for your bug report. This issue has been addressed in the documentation. The updated documentation will appear on our website shortly.

I'll remove the default from the text and let the table speak for itself.
