Gary, in these tests you have been using the 'float()' function for creating numbers. Would it be better to create a large number of IEEE-754 bit patterns (as strings) covering all number types (and possibly multiple +/- NaNs with different bits in the mantissa) and then convert these to 64 bit floats taking endianness into account? This should be more portable than using the 'float()' function and give us much better control of the floats.
