It's tough to say. Looking at the current situation for retrieving double
values with getInt() the current driver will throw an Exception on a out
of range value because it starts with a String and uses Integer.parseInt()
on it. Contrast this with the result of
Double d = new Double(Double.MAX_VALUE);
System.out.println(d.intValue());
which truncates the double to Integer.MAX_VALUE. The javadocs are
useless, but I prefer the Exception to silent truncation, so I would
suggest getByte can be used on any integer value of -128 to 127 regardless
of its storage form (like text). The question of comparing floating point
numbers should be the same, but we may run into problems when 1 is
represented as 1.00000001.
