The number_format function in PHP seems to round by default. My understanding is that this function is useful for separating every three numbers with a comma. Like 1403423 becomes 1,404,423 when using number_format. So, if I have a large number that I want rounded to two decimal places, how can I do this and still have the commas properly displayed? Desired behavior: 12042.529 --> 12,042.53 $a=12042.529; echo number_format($a,2,'.',','); 来源： https://stackoverflow.com/questions/19019409/php-number-format-and-rounding

Yes. I know. Those are localization settings... But I wont tell my client to change localization settings for just my app. So how to convert those numbers? Or how to change number formatting for given range. (Need dots there, user may input comas or dots, or even numbers where commas just separate like 1,000,000.00 ...) EDIT: Circumvented whole issue by CStr(), and passing on the strings. If this is purely for display purposes then you can use custom format strings on the cells. Then your users can continue to use their localization settings that they are used to for inputting numbers. I think

The Single UNIX Specification Version 2 specifies the sprintf 's format ' -flag behavior as: The integer portion of the result of a decimal conversion ( %i , %d , %u , %f , %g or %G ) will be formatted with thousands' grouping characters [ 1 ] I can't find the format ' -flag in the c or the c++ specifications. g++ even warns : ISO C++11 does not support the ' printf flag The flag is not recognized to even warn about in Visual C; printf("%'d", foo) outputs : 'd I'd like to be able to write C-standard compliant code that uses the behavior of the format ' -flag.
