And even the former apparently isn't guaranteed on all hardware. I found this gem in the Java documentation, I don't know which processors actually do this: >"Arithmetic operations on signaling NaNs turn them into quiet NaNs with a different, but often similar, bit pattern. However, on some processors merely copying a signaling NaN also performs that conversion. In particular, copying a signaling NaN to return it to the calling method may perform this conversion."
