arrays - Why doesn't the sort function of javascript work well? -

-

यह साधारण जावास्क्रिप्ट 

  var x = नया अर्रे (); एक्स [0] = 2.73; एक्स [1] = 11.17; X [2] = 3.12 x.sort (); के लिए (var i in x) चेतावनी (x [i]);

परिणाम उत्पन्न करता है: 11.17, 2.73, 3.12 के बजाय 2.73, 3.12, 11.17 ।

क्यों वह है और मैं इसे कैसे ठीक कर सकता हूं?

धन्यवाद अग्रिम!

यह वर्णानुक्रमिक रूप से सॉर्ट करना, अपने स्वयं के सॉर्टिंग फ़ंक्शन को पार करने का प्रयास करें: 

  var x = new Array (); एक्स [0] = 2.73; एक्स [1] = 11.17; एक्स [2] = 3.12; NumberSort = फ़ंक्शन (ए, बी) {वापसी a - b; }; x.sort (numberSort); के लिए (var i में x) {चेतावनी (x [i]); }

c++ - Qt-how to convert a QByteArray to struct -

I need to convert a QByteArray into a structure. I have such a structure: struct mavlink_attitude_t {/// & lt; Summary & gt; Timestamp (millisecond from system boot) & lt; / Summary & gt; Quint 32 Time_boot_ms; /// & lt; Summary & gt; Roll angle (rad, -pi .. + pi) & lt; / Summary & gt; Float roll; /// & lt; Summary & gt; Pitch angle (red, -p + + pi) & lt; / Summary & gt; Boat pitch; /// & lt; Summary & gt; Angle of O (Red, -P. + Pi) & lt; / Summary & gt; Float yao; /// & lt; Summary & gt; Angular Speed ​​Roll (Rod / S) & lt; / Summary & gt; Float rollspeed; /// & lt; Summary & gt; Pitch angular momentum (rad / s) & lt; / Summary & gt; Float pitchspid; /// & lt; Summary & gt; Yoga's angular momentum (RD / S) & lt; / Summary & gt; Float Yspeed; }; And I come from a Quetbeat Serial Port. I was already using the union but I think it can not be used for QByteArray, i...

c++ - What exceptions does boost mapped_file_source throw? -

-
Boost map_file_source, for example, throws an exception file not found. Is the exception square really throwing it? It does not seem to say in the documentation, unless I miss something. Edit: Test case: #include & lt; Boost / iostreams / device / mapped_file.hpp & gt; Int main (int argc, char ** argv) {boost :: iostreams :: mapped_file_source file; File.open (argv [1]); Return 0; If mapping fails, code mapped_handle_ = :: CreateFileMappingA (handle_, NULL, defense, 0, 0, zero); If (mapped_handle_ == NULL) cleanup_and_throw ("failed to create mapping"); Eventually will boost: iostreams :: detail :: throw_system_failure (msg); i.e. Sub-class of std :: exception In this case, it is std :: ios :: failure : BOOST_IOSTREAMS_FAILURE should be std :: ios_base :: Failure to expand, and otherwise the std :: exception for the appropriate derived class.
