how to transform decial point "3.15" to "3,15" comma?
Hello everyone, I am making a registry of real amounts,
and need trasformar fractional numbers,
so print coretamente.
there is some routine that do this?
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
