For issue #1483, refactors formatting of col1 and row1 variables to avoid issues with LC_NUMERIC auto-formatting float values.

Decided to use %03u to keep precision at 3 digits, used %03u over %.3u for better code readability in the format string.

I've been experimenting with this - I think using the proper locale for numeric is the best way to go, otherwise we'll have to change lots of lines of code just to get what the C library gives us for free. I pushed a one-liner comment to use the POSIX locale.

Here's a trivial test:

#include <stdio.h>
#include <locale.h>

int main() {
    float col1 = 3000000000000;
    setlocale (LC_ALL, "en_DK.utf8");
    printf ("%1.3f\n", col1);
    setlocale (LC_NUMERIC, "POSIX");
    printf ("%1.3f", col1);
}

Which outputs:

3000000053248,000
3000000053248.000

Hopefully this will fix this issue everywhere.

Oh I see! Right, I was thinking that fixing every sprintf eventually would be tedious. Well, thank you for your help with all this!
