/*  These inline functions may fail to return expected results if unsafe
    math optimizations like those enabled by -ffast-math are turned on.
    Thus, (somewhat surprisingly) you only get the fast inline
    implementations if such compiler options are NOT enabled.  This is
    because the inline functions require the compiler to be adhering to
    the standard in order to work properly; -ffast-math, among other
    things, implies that NaNs don't happen, which allows the compiler to
    optimize away checks like x != x, which might lead to things like
    isnan(NaN) returning false.
