"you can't". the answer "why this?" javascript implementation of math.sin not determined. see http://www.ecma-international.org/ecma-262/5.1/#sec-15.8.2.16 specifically "sin (x) returns implementation-dependent approximation sine of x. argument expressed in radians." (my italics). but experimentation suggests modern browsers use 1 of 2 implementations, chrome being different (and seemingly more accurate than) other browsers.

so i'm trying echo each row of users 1 of databases @ website set on wamp server, version 2.5. wrong, i've googled , search site's posts... don't think there's been problem quite 1 addressed yet. in practice of using php following tutorials/exercises, had of course found mysql prefers either pdo or mysqli these days, decided give shot @ using mysqli. the weird thing is, i've included php file configures mysql connection, , know connection variable being called properly, since i've printed out result of query variable being assigned to: mysqli_result object ( [current_field] => 0 [field_count] => 3 [lengths] => [num_rows] => 1 [type] => 0 ) above output when use: print_r($db_con->query("select * users")); yet when try assign result variable, $user_rs, , print value of variable, "notice: undefined variable: user_rs in c:\wamp\www\index.php on line 58." here files. dbconfig.php: <?php $db_con= ...

i'm learning use github , here's problem. i uploaded program github (git add, commit, push). noticed files in 1 of folders missing, replaced .gitignore the contents of "src" folder should follows: src -> model, controller model -> x.java, y.java z.java controller -> w.java instead of above, there single .gitignore file in src. contents of file like: /model/ /controller/ why did happen , how can fix this? that can happen instance egit: preference settings under team > ignored resources can define "derived" flag, generate .gitignore. if model , controller folder considered "derived" (ie "generated"), egit might have generated .gitignore. to fix it, check preferences , also git add --force folders, delete .gitignore, commit , push.

i new @ programming in c++, , have come across problem can't solve. trying create error message whenever user inputs integers instead of characters. problem is, integers being accepted , assigned char strings reason.. thought point of defining strings int or char etc. let compiler know values accepted. let me know i'm doing wrong? int x, input = false; char check[size], str[size]; cout << "enter 1 word: "; cin >> str; while (!cin) { cout << "\nerror: must enter 1 word characters. \n\nre-enter: "; cin.clear(); cin.ignore(256, '\n'); cin >> str; } a char 1-byte interpretation of integer according ascii value (i.e. integer 68 ascii value character 'd'). other ascii values can found here . for code, need create function loops through inputted string , checks see if of characters not letters. for example: for (int = 0; < strlen(str); i++) { if ((int)str[i] < 65 || ((int)str[...

i working on project ibeacon tag , rfduino board (is arduino variant). my mission receive ibeacon signal info (rssi) on rfduino. first did, test if can receive data rfduino following code , works fine, receives bluetooth le data. but not know how receive ibeacon data information. my question: possible receive ibeacon signal (rssi) or ibeacon info rfduino if yes, how? if no possible receive ibeacon signal using normal arduino hc-05 board (regular bluetooth board)? the code void setup() { serial.begin(9600); rfduinoble.devicename = "device1"; rfduinoble.begin(); } void loop() { } void rfduinoble_onreceive(char *data, int len) { serial.println(data[0]); } rfduino reference link . after long time research , try , fail, short answer no . more details ibeacon bluetooth le broadcaster , can discovered central or observer. many bluetooth le devices here including rfduino device pure peripheral device, not possible use discover ibeacon. ...
