Hello everyone, I am making a registry of real amounts, and need
trasformar fractional numbers, so print correctly. there is some
routine that do this?
why don't do just this:
void main () {
import std.stdio;
import std.string;
import std.array;
string s = %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.c.locale;
void main()
{
setlocale(LC_NUMERIC, );
writeln(3.5); // 3,5
}
You can change/see current decimal separator using (assuming
