Solution 2

If you uses parameterised queries you would not have this problem, as the correct values will be sent to the database.

C#

MySqlCommand cmd = new MySqlCommand("INSERT INTO youTable (numberOfDays) VALUE (@numberOfDays)", yourConnection);
cmd.Parameters.AddWithValue("@numberOfDays", numberOfDays);

This assumes that numberOfDays is your float value.

Solution 1

SQL decimal types are fixed point where as the System.Decimal type is floating point.
However, even then, System.Decimal is the closest match.
