Answer 1

First of all, the fact that the value in the database is a float does not mean that it also fits in a Java float. Float is short for floating point, and floating point types of various precisions exist. Java types float and double are both floating point types of different precision. In a database both are called FLOAT. Since double has a higher precision than float, it probably is a better idea not to cast your value to a float, because you might lose precision.

You might also use BigDecimal, which represent an arbitrary-precision number.
