Format input as number with locale in Angular 6

由 夙愿已清 提交于 2019-12-08 08:14:40
问题 I am trying to format a number in a text input in the locale of the user. I tried to use DecimalPipe and a custom self-made pipe and both work at first. The problem is, as soon as the number is formated into a string, the pipe doesn't work anymore since it is supposed to be applied on a number. So for example when I type 1234.23 , it displays 1 234,23 but the DecimalPipe doesn't work on 1 234,23 and I get the NaN error. I didn't find anything that allows me to turn back the formatted text

问题 I am facing problem while opening a downloaded CSV file in Excel under window 7 for above locale. Sometime the number is treated as date and all the cells are misaligned and formatted incorrectly.

I invested the issue and it came to know that there is a mismatch between format defined on Windows 7 system and locale retrieved from ServletRequest#getLocale() for Norwegian,

问题 Proper way to format the numbers in ORACLE stored procedures. I need to display currency fields with 2 decimals. Expected output is as follows: 0 > 0.00 5 > 5.00 1253.6 > 1253.60 1253.689 > 1253.69 Below worked for me: select to_char(9876.23 , 'fm999990.00') from dual; But this has the issue of hard coding a bunch of 9s. If I give a larger number it will be displayed as "##############" Is there any other way I can do this? 回答1: I need to display currency fields with 2 decimals. Ensure you

问题 I have an app which runs the following two lines of code upon starting: DecimalFormat decim = new DecimalFormat("#.00"); return Double.parseDouble(decim.format(totalNumberOfCredits)); When I start the app on my American phone, the value of decim.format(totalNumberOfCredits) is .00 .

Boost's lexical_cast From double to string Precision

由 痞子三分冷 提交于 2019-12-07 10:29:42
问题 I'm working with a library that unfortunately uses boost::lexical_cast to convert from a double to a string . I need to be able to definitively mirror that behavior on my side, but I was hopping to do so without propagating boost . Could I be guaranteed identical behavior using to_string , sprintf , or some other function contained within the standard? 回答1: The boost code ends up here: bool shl_real_type(double val, char* begin) { using namespace std; finish = start + #if defined(_MSC_VER) &&

How to print formatted float in obj-c?

由 谁说我不能喝 提交于 2019-12-07 06:45:05
问题 How to print a float in Objective-C as, for example, 3.45 instead of 3.45555555555 ? 回答1: Try formatting the float like this: NSLog(@"%.2f", myFloat); The % sign means this will be replaced by the corresponding argument following ( myFloat ). The .2 means 2 decimal places, and f means a float datatype. Take a look here for more detail. Objective-C's NSLog is very similar to C's printf , with the main exceptions being that you must use an Objective-C string literal ( @"…" ) and you should use

Is there a way to get the decimal and thousands separator in ECMAscript Internationalization API?

由 痞子三分冷 提交于 2019-12-07 06:04:47
问题 I'm trying to use the new Javascript internationalization API, and would like to know if there is a way to get the decimal and thousands (grouping) separator for a Intl.NumberFormat instance? There is a resolvedOptions method on the object, but that does not provide the symbols. In case anybody's wondering, then for en-US, these would be a comma , and period . , such as in 1,000.00 . 回答1: I'm afraid ECMA-402 standard does not define the API that let you access separators. There is also
