[format] negative 0?
I use boost 1.32 with VS 6.0 (sp5) on Windows2000. If I try this : int anIntValue(-0); std::cout << anIntValue << '\n';\ I get : 0 And, if I try this : boost::format formatTest("My test : %0.0f \n"); double theValue(-0.0002); std::string theString = boost::io::str(formatTest % theValue); I get : "My test : -0" Is it the right behavior? I was expecting the same result (simply a 0). Maybe I am wrong... Thank you for any advise / suggestion. Alain

Yes, it is expected to print that, because the value you print is not zero, but a small negative value. Even if there is some rounding done, a negative sign is usually left to indicate that. -- François Duranleau LIGUM, Université de Montréal "Oh mighty one...
