Gnome desktop setting

[Chiara Zaniboni <chiara zaniboni wirelessfuture it>]

I'v installed Mandrake 9.1 on a PC and I use gnome desktop. I try to run 
a GUI application developed with Glade (and C language) and when I 
perform ad istruction like
fprintf(stderr,"%lf",var);
the output that I see on the gnome terminal is like
750,82 (a comma separates the decimal part of the number from the 
integer one)
and not
750.82 (a dot separates the decimal part of the number from the integer one)
as I desire.
The comma is a problem for the entire application. I suppose that this 
can be due to a setting of the gnome desktop (infact non-GUI 
applications developed in C language work correctly and the printf 
istructions produces dot-separated number on the terminal): is this true?
Hov can I solve the problem?

Thank-you!

Chiara
