Hi，I have a issue that: when a floating number changes, then stores the new value to database, but in the database, i found many records, the same tag, different time, small changes in floating point numbers;  
So, how to stop it?

With a format string that shows no more than two decimal places, your deadband should not be smaller than 0.01.
