Fortran decimal and thousand separator

由 自作多情 提交于 2020-01-05 15:05:31
问题 Is there a way to change the period decimal separator for a comma?. Also, how can I make the output numbers have a thousand separator?. This could be a comma, a period, a space ... 回答1: You can write a C++ function which will convert the number in a string in you current locale for you. #include <string> #include <iomanip> #include <sstream> class SpaceSeparator: public std::numpunct<char> { public: SpaceSeparator(std::size_t refs): std::numpunct<char>(refs) {} protected: char do_thousands

由 核能气质少年 提交于 2020-01-05 08:44:10
问题 I would like to export a HTML table to XLS and at the same time retain all formatting. The following code seems to be working, except that the hilight is lost on export. How do I keep it in place? <html> <head> <title>TODO supply a title</title> <meta charset="UTF-8"> <script src="http://code.jquery.com/jquery-1.9.1.js"></script> </head> <body> <div id='data'> <table border='1'> <tr> <td> <strong>Greeting</strong> </td> <td> <strong>Message</strong> </td> </tr> <tr> <td> Hello </td> <td>

Is(Are) there some character(s) I can put in my code that Java will ignore, but Eclipse would detect it as a part of code that has to have additional indentation

PHP strptime format bug?

由 十年热恋 提交于 2020-01-05 01:41:14
问题 I am wrestling with a php 5.2.6 problem. An api we use returns dates in this format DDMMYYYYHHMM. Exactly that format, fixed length, no delimiters. However, in my experimentation, this format seems to break strptime, which returns a false (fail) when I feed it a date in this format. It can reproduced, at least on my system, with this example: $format = "%d%m%Y%H%M"; echo print_r(strptime(strftime($format,1225405967),$format),true); If I add any character between the date and the time, it

C++ decimal output formatting

由 寵の児 提交于 2020-01-04 15:28:59
问题 i'm writing a double value to a file. The numeric value is written with a point as a decimal separator. I would like to use a comma. How i can do that? 回答1: The usual way is to use a locale with the decimal separator set to the comma. If your machine is configured for that generally, you can probably just use the nameless locale for it: std::cout.imbue(std::locale("")); std::cout << 12345.67; 回答2: You can find the answer in an earlier question This basically changes the locale used by the
