yes i have, but it is master slave replication.so when master is updated slave will also update.Other than that i dont have any backups

well, you have lost precision and so lost the original value in the current table structure. There is no way to get precision back once it has been lost :S

When you are not sure of the result of an operation always try it on a copy of the real database so you would hopefully never have such problems.
