These are dependent on floating point optimizations. Generally the
failures are due to whether an intermediate value in the calculation are
stored or not, and that depends on GCC version and CPU type. It's not
something that C++ defines a semantic for. There are some compiler flags
to fix it, but in the end it may be more sensible to drop the tests and
accept that very large numbers may produce different results.
