Floating-point Settings in Worker Threads May Differ from Master Thread for OpenMP, TBB and Intel Cilk Plus

Worker threads created by OpenMP, Intel Cilk Plus or Intel Threading Building Blocks may have different initial floating-point environments compared to the master thread that spawned them. This can lead to slight differences in floating-point results.
