mysql - Strange problem with double in database mysql

Question

I have some database table double:

 (somenumber float(11,2) DEFAULT '0.00' NOT NULL,)

If I try to save number "1.91" or "1.93" I get error like:

These fields of record 95 in table "tx_xxx_yyy" have not been saved correctly: somenumber! The values might have changed due to type casting of the database.

If I save muber "1.92" or "1.94" I do not get error.

Is this a MySql bug?

Thanks Martin
