Detailed Description

template<int Y, int InfX = 0, int SupX = ((Y==1) ? 1 : Y/2), bool Done = ((SupX-InfX)<=1 ? true : ((SupX*SupX <= Y) && ((SupX+1)*(SupX+1) > Y)))>
class Eigen::internal::meta_sqrt< Y, InfX, SupX, Done >

In short, it computes int(sqrt(Y)) with Y an integer. Usage example:

 meta_sqrt<1023>::ret
