Hello everyone, I am making a registry of real amounts,
and need trasformar fractional numbers,
so print coretamente.

 how to transform decial point "3.15" to "3,15" comma?


 Hello everyone, I am making a registry of real amounts, and need=20
 trasformar fractional numbers, so print correctly. there is some=20
 routine that do this?


why don't do just this:

  void main () {
    import std.stdio;
    import std.string;
    import std.array;
    string s =3D "%s".format(3.14).replace(".", ",");
    writeln(s);
  }

but i believe that separator is locale-dependend, so maybe you should
just change locale at program startup?

Is the , (comma) the system decimal separator? if so, you can use 
C intero and include locale.h header (in D, the respective 
module) call setlocale(LC_NUMERIC, "") function and then 
printf("%g", 3.5) will output (if decimal separator is the 
comma): 3,5

I haven't tested it in D but I think D's writefln() will behave 
exactly same as C's printf().. but it didn't you're free to call 
C's printf()

The code is the following:

import std.stdio;
import std.c.locale;

void main()
{
	setlocale(LC_NUMERIC, "");
	writeln(3.5); // 3,5
}

You can change/see current decimal separator using (assuming
Windows) http://www.softwareok.com/?seite=faq-Win-7&faq=78
