Hello, I'm losing precision when I send a double to a mysql database from a Java program trough JDBC. Code: stmt.setDouble(i+3,((Double)value).doubleValue()); I use a prepared statement. Now, if I print out the double in java before sending it to the MySql database this is what it looks like: 1277.00143924408 (11 decimal digits) When I look in the database, this is what the value looks like: 1277.00143924 (8 decimal digits) The type of the column is "double"(without any precision or digits specification). Now the big question is: what happened to the last 3 decimal digits? Or is this just a display problem? Does the database only display 8 decimal digits by default? So I changed the type in the table to "double(40,20)" and now the value in the database changes to: 1277.00143924000008155417 (exactly 20 decimal digits) Ok, next I set the type to "double(40,11)" and I get: 1277.00143924000 (11 decimal digits). Anyway, I lose the last digits. WHY? I thought that the MySql double type has the same precision than the java double type? Whats wrong here? Thanks for any answers...
