I've got a field called "shipping" that's set as a FLOAT at 5,2. Due to an error in my PHP (not rounding a calculation), I found that INSERTS were being saved as 2.9800000035 and somehow that amount is even being saved in the database (shouldn't it have been dropped to 2 places with the 5,2?)
Now I'm trying to fix the problem. I temporarily changed the structure to 20,17 and can clearly see the stray numbers. In phpmyadmin I issued:
SELECT shipping from order WHERE shipping > 2.98 AND shipping < 2.99;
and get tons of results. So then I thought it would be simple to fix. I did:
UPDATE order SET shipping = '2.98' WHERE shipping > 2.98 AND shipping < 2.99;
and I get no changes. Why? And how to fix the entries in the database?
