Hi Niclas,
Your idea seems reasonable. I believe we already have a rounding algorithm in the tests, so putting in some explicit known tricky cases would be a good test.

We decided to use these values for double in the AllTypes class: public static final double DOUBLE_SMALLEST = -9999999999999.9; public static final double DOUBLE_LARGEST = 9999999999999.9; public static final double[] double_values = { DOUBLE_SMALLEST, DOUBLE_LARGEST, 0.0, 100.0, 100.0, 50000000.0, -234234.234, 1000000000.0, 350.5, -25.5 };
I'd be happy to use DOUBLE_LARGEST and DOUBLE_SMALLEST from AllTypes.
What do you all think?
May I suggest that 0.1 and -0.1 are included in the suite of numbers??
Over the years, they have been involved in a lot of rounding issues (granted;
because people errenously use floats and doubles for monetary and other
fixed-point decimal numbers) and I would be happy if the expected behaviour
is "documented" in tests.
Cheers Niclas
