I want to create a string in C++ with the following format:
string + numbersWithFormatAndThousandSeparator + string
I am not sure whether std::string or snprintf() provides format like that especially the thousand separator. Could someone help me with this?
452
The character used as the thousands separatorIn the United States, this character is a comma (,). In Germany, it is a period (.). Thus one thousand and twenty-five is displayed as 1,025 in the United States and 1.025 in Germany. In Sweden, the thousands separator is a space.
You use the format specification language expression '{:,}' to convert the integer number 1000000 to a string with commas as thousand separators. The outer part, the curly brackets '{...}' says to use the number passed into the format() function as a basis of the formatting process.
The decimal separator is also called the radix character. Likewise, while the U.K. and U.S. use a comma to separate groups of thousands, many other countries use a period instead, and some countries separate thousands groups with a thin space.
Fast and easy way:
std::ostringstream ss;
ss.imbue(std::locale("en_US.UTF-8"));
ss << 1033224.23;
return ss.str();
Would return a string "1,033,244.23"
But it requires en_US.UTF-8 locale to be configured on your system.
