Information
This function takes an integer, and returns a string formatted with commas (','), to make it easier to read. This can be very useful for scripts that use money, such as a lottery script.
Parameters:(number)
number | The integer you wish to format |
Return Values:
A string with commas placed after every three numbers
AddCommasToInt(1234567);
Example
AddCommasToInt(1234567); // Returns 1,234,567 AddCommasToInt(1234); // Returns 1,234 AddCommasToInt(123); // Returns 123
Definition
/** * Adds thousands separators to a number and returns the result as a string. It * seems only logical to start from the back and count groups of 3 until the * front is reached. Works with any positive or negative 32 bit integer. * * @param int number value to add seperators to * @param string separator the separator char * @return string the formatted string * @author Vince */ AddThousandsSeparators(number, const separator[] = ",") { new output[15]; // longest possible output given 32 bit integers: -2,147,483,648 format(output, sizeof(output), "%d", number); for(new i = strlen(output) - 3; i > 0 && output[i-1] != '-'; i -= 3) { strins(output, separator, i); } return output; }
