Ah, right. I also thought about that first but than started worrying that it could produce unnecessary zeros if the loop iterates at least once and exits with r being zero, but now I see that this cannot happen since if the loop condition was true, r >= 10000 and it has been divided by 10000 in the loop so now it's at least 1. -- Best regards, _ _ .o. | Liege of Serenely Enlightened Majesty of o' \,=./ `o ..o | Computer Science, Michał “mina86” Nazarewicz (o o) ooo +----<email/xmpp: m...@google.com>--------------ooO--(_)--Ooo--
