 #define Ring1_Intrinsic_Fp_ExponentMask_suffix /* Implementation */ 
where suffix is either f32 (for the type float) or f64 (for the type double).
For suffix f32: Symbolic constant evaluating to a uint32_t value. Masks the exponent bits of the raw bits representation of a single-precision floating-point value (8 bits from index 30 to 23).
For suffix f64: Symbolic constant evaluating to a uint64_t value. Masks the exponent bits of the raw bits representation of a double-precision floating-point value (11 bits from index 63 to index 52).
