Unfortunately it seems that not even the new-style formatting with float.__format__ supports this. The default formatting of floats is the same as with repr; and with f flag there are 6 fractional digits by default: >>> format(0.0000000005, ‘f’) ‘0.000000’ However there is a hack to get the desired result – not the fastest one, but … Read more
You’re not assigning the parsed float back to your value var: value = parseFloat(value).toFixed(2); should fix things up.
NUMBER (precision, scale) If a precision is not specified, the column stores values as given. If no scale is specified, the scale is zero. A lot more info at: http://download.oracle.com/docs/cd/B28359_01/server.111/b28318/datatype.htm#CNCPT1832
Use std::locale with std::stringstream #include <iomanip> #include <locale> template<class T> std::string FormatWithCommas(T value) { std::stringstream ss; ss.imbue(std::locale(“”)); ss << std::fixed << value; return ss.str(); } Disclaimer: Portability might be an issue and you should probably look at which locale is used when “” is passed
It turns to be quite simple: My code: {% set proc_err = nb_err|length / sum * 100 %} ({{proc_err|float}}%) Can be changed a bit with: {% set proc_err = nb_err|length / sum * 100 %} ({{‘%0.2f’ % proc_err|float}}%) or using format: ({{‘%0.2f’| format(proc_err|float)}}%) Reference can be found here on jinja2 github issue 70
Checkout the following article on MSDN about examples of the N format. This is also covered in the Standard Numeric Format Strings article. Relevant excerpts: // Formatting of 1054.32179: // N: 1,054.32 // N0: 1,054 // N1: 1,054.3 // N2: 1,054.32 // N3: 1,054.322 When precision specifier controls the number of fractional digits in the … Read more
There isn’t an easy way to control the formatting Excel applies when opening a .csv file. However listed below are three approaches that might help. My preference is the first option. Option 1 – Change the data in the file You could change the data in the .csv file as follows …,=”005”,… This will be … Read more
I believe that the stringWithFormat specifiers are the standard IEEE printf specifiers. Have you tried [NSString stringWithFormat:@”%02d”, 1];
Use DecimalFormat. DecimalFormat is a concrete subclass of NumberFormat that formats decimal numbers. It has a variety of features designed to make it possible to parse and format numbers in any locale, including support for Western, Arabic, and Indic digits. It also supports different kinds of numbers, including integers (123), fixed-point numbers (123.4), scientific notation … Read more
For a general-purpose¹ solution you need to preserve 339 places: doubleValue.ToString(“0.” + new string(‘#’, 339)) The maximum number of non-zero decimal digits is 16. 15 are on the right side of the decimal point. The exponent can move those 15 digits a maximum of 324 places to the right. (See the range and precision.) It … Read more
