[boost] Fixed point integer proposal

Hi, Some years ago I wrote a fixed point template for transparent fixed point integer arithmetics and conversion. It worked well and performance was equal to that of native integer types, at least in MS VC++. The template takes a base type and the number of bits reserved for the fraction part and meta-programming works out boundary safe arithmetics and conversions. The template has been used in an image processing library, but lately I used it for seamless conversion of a 4+28 bit fixed point MAD-library decoded mp3-stream to the output buffer of the sound system, with a detour through a float-based sound effect. Would there be public interest in a template like that in the boost library? Soren
