not exactlly, sometimes you get the 1 difference correctly so, you will introduce an error for such cases, and on some compillers (bcc) for some cases you get an error because it don´t know which version to instantiate Sqrt<N,X,XP1,XP1> or Sqrt<N,X,X,XP1> On Thu, 27 Jan 2005 22:55:49 -0500, Jason Hise <chaos@ezequal.com> wrote:
Would the following work in all cases? My assumption is that if an oscillation is going to occur, the two numbers will always be off by exactly one.
template < unsigned int N, unsigned int X = 1, unsigned int X2 = ( X + N / X ) / 2, unsigned int XP1 = X + 1 > struct Sqrt { enum ValueStorage { Value = typename Sqrt < N, X2 > :: Value }; };
template < unsigned int N, unsigned int X, unsigned int XP1 > struct Sqrt < N, X, X, XP1 > { enum ValueStorage { Value = X }; };
template < unsigned int N, unsigned int X, unsigned int XP1 > struct Sqrt < N, X, XP1, XP1 > { enum ValueStorage { Value = X }; };
