Correctness: floating point equality using bits instead of ==.
Special values for float and double make it inaccurate to test the equality with ==.
The main Java library uses the standard Object.equals() implementation for all fields,
which for floating point fields means Float.equals() or Double.equals(). They define
equality as bitwise equality, with all NaN representations normalized to the same bit
sequence (and therefore equal to each other). This test checks that the nano
implementation complies with Object.equals(), so NaN == NaN and +0.0 != -0.0.
