I just installed VC++ Express and now when I try to do this: if (vector_length > std::numeric_limits<double>::epsilon()) I get tons off errors like: c:\documents and settings\daniel lowengrub\my documents\visual studio 2005\projects\nehegl\nehegl\vector2d.h(248) : error C2039: 'numeric_limits' : is not a member of 'std' c:\documents and settings\daniel lowengrub\my documents\visual studio 2005\projects\nehegl\nehegl\vector2d.h(248) : error C2065: 'numeric_limits' : undeclared identifier c:\documents and settings\daniel lowengrub\my documents\visual studio 2005\projects\nehegl\nehegl\vector2d.h(248) : error C2062: type 'double' unexpected c:\documents and settings\daniel lowengrub\my documents\visual studio 2005\projects\nehegl\nehegl\vector2d.h(248) : error C2039: 'epsilon' : is not a member of '`global namespace'' But in dev this works? is there a differents between the stds? What should I do? Thanks.
