numbers

Must a C++ implementation set the chars '0'-'9' to have contiguous numeric values, i.e. so that: '0' -> 0+n '1' -> 1+n m -> m+n '9' -> 9+n I cannot find it mentioned in the documentation of isdigit ([classification] (22.3.3.1 Character classification)) * , nor can I find it in the locale documentation (but maybe I did not look hard enough). In 2.3 Character sets, we find that The basic source character set consists of 96 characters: the space character, the control characters representing horizontal tab, vertical tab, form feed, and new-line, plus the following 91 graphical characters But it

I am thinking if there is anyway to generate a set of random numbers of which the sum is always a constant. For example, 20 can be divided into 5 numbers ( 1, 2,3,4,10) I don't care what each of the 5 numbers is as long as their sum is equal to 20. Is there anyway to do so programmatically? To get a uniform distribution, the trick is to think of your sum as a number line, and rather than generating random numbers for the segments, generate n-1 numbers as points along the line, and subtract to get the segments. Here's the function from ojrandlib : static int compare(const void *a, const void *b

Is there a standard way to make screen readers spell out numbers? I am currently using NVDA and Firefox and have the following telephone number <p>01234 567890</p> This is read as Zero one two three four five hundred and sixty seven thousand eight hundred and ninety This is quite confusing to the listener. I would like some way of specifying that the screen reader should spell out the number like Zero one two three four five six seven eight nine zero I don’t know if (or which) screen readers support these, but (in an ideal world) they should . CSS: Aural CSS 2.1: speak-numeral: digits; Speak

Is there any way to select the numbers (integers) that are included between two numbers with SQL in Oracle; I don't want to create PL/SQL procedure or function. For example I need to get the numbers between 3 and 10. The result will be the values 3,4,5,6,7,8,9,10. Thx. This trick with Oracle's DUAL table also works: SQL> select n from 2 ( select rownum n from dual connect by level <= 10) 3 where n >= 3; N ---------- 3 4 5 6 7 8 9 10 The first thing I do when I create a new database is to create and populate some basic tables. One is a list of all integers between -N and N, another is a list of

I'm developing a PhoneGap Android mobile application using jQuery, JavaScript and HTML. I want to get the mobile IMEI. I have tried this code from this Tutorial . I am getting the number like this: 97734a345d234d . I have checked my device to get IMEI number using *#06# . I don't know whether it is correct or not. Fetch the IMEI number in the class which extends DroidGap class and save the value of imei number in static member and then access this static field from where ever you want... example code is here public class MyApp extends DroidGap { private static String imei; @Override public

Is there any clean way of setting numpy to use float32 values instead of float64 globally? Not that I am aware of. You either need to specify the dtype explicitly when you call the constructor for any array, or cast an array to float32 (use the ndarray.astype method) before passing it to your GPU code (I take it this is what the question pertains to?). If it is the GPU case you are really worried about, I favor the latter - it can become very annoying to try and keep everything in single precision without an extremely thorough understanding of the numpy broadcasting rules and very carefully

I am using a HTML5 input box with type="number" . Regarding to some documentations, it should be possible to enter a number with comma (not with period) if I also use the lang="" attribute. It is working in Firefox, but not in Chrome (does not accept a comma). How can I get Chrome to accept the comma in the input box. My problem is that our German users expect that they can enter a comma instead of a period there. https://jsfiddle.net/byte2702/y3Lpfw7m/ Please enter a number with comma: <br/> <input id="num" type="number" step="any" lang="de" pattern="-?[0-9]+[\,.]*[0-9]+" /> As of now (30/08
