On arm-none-eabi I'm seeing a failure for the long double type and inputs:
{ 1e-2l, 1e-4l, 1e-4l, 0.010000999950004999375l }
The abs(frac) is higher than the toler: 1.73455e-16 vs 1e-16. Is that a
reasonable difference? Should we raise toler3 to 1e-15?
The last line is also too high:
{ 2147483647.l, 2147483647.l, 2147483647.l, 3719550785.027307813987l }
Yields a frac of: 1.28198e-16
Those are the only ones that pass the 1e-16 threshold.
Cheers,
Andre
