Hello everyone,

I'm trying to split an integer into a integer with decimal points (or char[]
with decimal points). I already know that I can do this with
std.format.doFormat() but I don't know how I can use this to convert my int
(for example... 10000) to 10,000.

I hope anyone can help me :)

In this case... thanks so much for help

Well, integers don't have anything following the decimal, so there's nothing to
do really. Unless you want to convert the integer to a string and append ".00"
or something. Perhaps you want to convert the integer to a string and insert
thousands separators? If so, you'll want to loop from the end of the string
towards the beginning, inserting a comma every 3 characters.

char[] AddCharEvery(char[] str, char c, int i)
{
    if(str.length > i) return AddCharEvery(str[0..$-i],c,i) ~ c ~ str[0..$-i];
    else return str;
}

or


char[] AddCharEvery(char[] str, char c, int i)
{
   if(str.length <= i) return str;

   auto ret = new char[str.length + (str.length-1)/i];

   int at = ret.length;
   while(str.length  > i)
   {
       ret[at-i..at] = str[$-i..$];
       ret[at-i-1] = c;
       at -= (i+1);
       str = str[0..$-i];
   }
   ret[0..at] = str;
   return ret;
}

//example
import std.stdio;
void main()
{
 writef("%s\n", AddCharEvery("100000000000000", ',', 3));
 writef("%s\n", AddCharEvery("10000000000000", ',', 3));
 writef("%s\n", AddCharEvery("1000000000000", ',', 3));
 writef("%s\n", AddCharEvery("100000000000", ',', 3));
}
