.... float x = 55; // stored as 54.999999... x = x + 0.5 - (x<0); // x is now 55.499999... int y = (int)x; // truncated to 55 C++11 also introduces std::round, which likely uses a similar logic of adding 0.5 to |x| under the hood (see the link if interested) but is obviously more robust.

This has never happened before. Usually it displays the error, but now it just gives me a 500 internal server error. Of course before, when it displayed the error, it was different servers. Now I'm on a new server (I have full root, so if I need to configure it somewhere in the php.ini, I can.) Or p...

...ncoding might sometimes be needed when interpreting user documents with unknown encodings, in the absence of other hints. This encoding should be used rarely, if at all. Note that some potential values here might result in unexpected encoding conversions of even fairly straightforward NSString cont...

...; (key, value) tuple of "first" element Please note that (at best of my knowledge) Python does not guarantee that 2 successive calls to any of these methods will return list with the same ordering. This is not supported with Python3. in Python 3: list(my_dict.keys())[0] -> key of "first" ...
