FE_TONEAREST is the correct default.  This has been the standard in
IEEE 754 since 1985; essentially all hardware since then will
implement it as the default, and essentially all numerical software
that relies on any rounding mode will rely on that as the default.

If the code doesn't work with FE_TONEAREST then there's something
wrong with the code, not with the choice of default rounding mode.
