Hello,
The function boost::chrono::floor() is documented: "This function round down the given parameter." Therefore I expect the assert in the following program to pass, but it fails:
#include <boost/chrono/floor.hpp> #include <cassert>
int main() { boost::chrono::nanoseconds const nsec( -1 ); boost::chrono::seconds const sec = boost::chrono::floor<boost::chrono::seconds>(nsec); assert( sec.count() == -1 ); }
Is this intended behavior? If yes, could the docs be updated to clarify this?
Hi, no, there is a bug with negative numbers. template <class To, class Rep, class Period> To floor(const duration<Rep, Period>& d) { + if (d<duration<Rep, Period>::zero()) + return duration_cast<To>(d)-To(1); + else return duration_cast<To>(d); } Please, coul dyou create a ticket so that I don't forget it. Thanks, Vicente
