As I said, I don't think non-deterministic implementations exist, but probabilistic rounding apparently has some attractive features, and it is certainly allowed by the standard. The idea is that you calculate (in principle) the exact result, and round up the last bit with probability equal to (ExactValue - ValueWithLSBitRoundedDown) / ValueOfLastBit (In practise of course you don't need to calculate an infinite number of bits. You keep calculating extra bits until you get a bit that doesn't match your random number generator bit stream. At that point you know whether you need to round up or down - regardless of what all the other bits from the value or the random number generator are). -- Martin Bonner Martin.Bonner(a)Pitechnology.com Pi Technology, Milton Hall, Ely Road, Milton, Cambridge, CB4 6WZ, ENGLAND Tel: +44 (0)1223 203894

boost::function overhead?
by Neal Becker 03 May '06

03 May '06

I'd like to use boost::function to wrap (pointer to) function to pass to template functions that expect function objects. I'm just wondering, though, if using boost::function wrapper will introduce additional overhead into the function call? example: template<typename in_t, typename out_t, typename func_t> inline void apply (in_t const& in, out_t out, func_t const&f) { typename boost::range_const_iterator<in_t>::type i = boost::begin (in); typename boost::range_iterator<out_t>::type o = boost::begin (out); for (; i != boost::end (in); ++i, ++o) *o = f (*i); } template<typename in_t, typename out_t> inline void phaseDouble (in_t const& in, out_t &out) { apply (in, out, lvalue_cast (boost::function<typename boost::range_value<out_t>::type (typename boost::range_value<in_t>::type)> (some function))); } }

Hi gurus, Under VC7.1/8, struct xxx : std::vector<int> { virtual void foo() = 0; }; void test(xxx& rng) { BOOST_FOREACH (int x, rng) { } } makes error, foreach.hpp(361) : error C2259: 'xxx' : cannot instantiate abstract class GCC3.4.4 compiles. Is this wrong code? -- Shunsuke Sogame

[MPL] bug in quote.hpp?
by Jaakko Järvi 03 May '06

03 May '06

Hi, Starting from line 61: template< typename T, bool has_type_ > struct quote_impl // GCC has a problem with metafunction forwarding when T is a // specialization of a template called 'type'. # if BOOST_WORKAROUND(__GNUC__, BOOST_TESTED_AT(4)) \ && BOOST_WORKAROUND(__GNUC_MINOR__, BOOST_TESTED_AT(0)) \ && BOOST_WORKAROUND(__GNUC_PATCHLEVEL__ BOOST_TESTED_AT(2)) There seems to be a comma missing from the last line, before BOOST_TESTED_AT(2), is that right?

Joel, I think showing the zip_iterator example I've been using would be very instructive, if not entirely representative of the library's full power: http://tinyurl.com/mrgub You could also link to these diffs to show how much simpler zip_iterator gets when we use fusion: http://tinyurl.com/qslyu I'll send you a slide set that you could use for inspiration if you like. -- Dave Abrahams Boost Consulting www.boost-consulting.com

Graph library concept check problem
by Matthias Troyer 03 May '06

03 May '06

Hi, Trying to compile our ALPS project sources (http://alps.comp- phys.org) with the CVS HEAD I encountered a number of problems with the BGL concept checking. In particular on MacOS X, using the Apple g+ + 4.0.1, I encounter problems in depth_first_search.hpp with: template <class Visitor, class Graph> class DFSVisitorConcept { public: void constraints() { function_requires< CopyConstructibleConcept<Visitor> >(); vis.initialize_vertex(u, g); vis.start_vertex(u, g); vis.discover_vertex(u, g); vis.examine_edge(e, g); vis.tree_edge(e, g); vis.back_edge(e, g); vis.forward_or_cross_edge(e, g); vis.finish_vertex(u, g); } private: Visitor vis; Graph g; typename graph_traits<Graph>::vertex_descriptor u; typename graph_traits<Graph>::edge_descriptor e; }; Somehow this tries to instantiate a default constructor for the visitor and the graph. Since some graph types do not have a default constructor and no default constructor should actually be required, I want to ask whether this is a bug in the compiler or in the concept checks?
