Gradebook calculates letter grades at 5 decimal places, and the Grade Letter settings only allows setting the Grade Letters as Integers. It would be great if we could enter decimals directly. I've left the issue as minor as you can work around the issue by editing the database.

My post from: http://moodle.org/mod/forum/discuss.php?d=122576
"Problem is you can't access the five decimal places from the user interface. You need to open up your database, go to mdl_grade_letters and adjust the cutoffs for the contextid of 1 for a sitewide change, or otherwise... work out which course it is for... unfortunately I am not sure how because the context id is not the same as the courseid.

Be aware that if you enter decimals manually in the DB they will work fine, but your editing screen with the dropdown will say 'unused'. If you view (not edit) the grade letters from a course however, you will see them represented as they are in the DB.

Of course it would be much easier if we can get the code changed to allow us to enter decimals directly into the Grade Letter cutoffs instead of having only a drop-down list. I noticed that the LSU gradebook allows this - I wonder if it can be merged in?"

Thanks for all your great work on Moodle!
