bind param problem in double values

If we want to save double type value, the value and the saved value is different than each other.
I want to save 12345.6 to the DB, but the saved value is 12345.5888888888889
It seems the bind param's problem and not related to the Jalno. See: https://dev.mysql.com/doc/refman/5.6/en/problems-with-float.html
