Ring1_Intrinsic_Fp_ExponentBits
#define Ring1_Intrinsic_Fp_ExponentBits_suffix /* Implementation */
where suffix is
either f32 (for the type float)
or f64 (for the type double).
Symbolic constant evaluating to a positive integer value denoting the number of exponent bits of an IEEE754 floating-point value.
That value is 8 for f32 and is 11 for f64.
