Ring1_Intrinsic_Fp_SignBits
#define Ring1_Intrinsic_Fp_SignBits_suffix /* Implementation */
where suffix is
either f32 (for the type float)
or f64 (for the type double).
Symbolic constant evaluating to an integer value 1 (both for suffix f32 and suffix f64),
denoting the number of sign bits both of a IEEE754 32 bit floating-point value and a IEEE754 64 bit floating-point value, respectively.
