Yep, they''re efficient.
Actually, they were optimised for Microsoft by engineers from Intel and AMD so they should be! They will take advantage of any SIMD instructions present on the CPU too (3DNow!, SSE, SSE2...).
The only place you could beat them with a custom routine would be for processing large sequential lists of data, particularly where you''re combining multiple calculations into one.
If you are doing it yourself, it''d be best to visit the Intel and AMD websites and download the already fully optimised source code they have.
