Not sure if this zero warning policy is in effect, but if so maybe Boost can have a look at use of __int64 and pow (e.g. boost::math::pow<2, __int64> gives a warning)?
Fixed in Trunk: please note that pow<2, __int64> returns double, the "fixed" version performs calculations at double precision internally as well. These aren't intended as *integer* routines if that's what you're looking for...
HTH, John.
Thx. We had that discussion here, that returning an integer would be more precise / faster, until somebody noticed that (32 bit) integers overflow very fast. So it is ok that integers are 'promoted' to double. Btw nice addition this function. I think it's twice as fast as using std::pow using VStudio 2008.
