Here's a neat way to always have nicely formatted money values!

Example:

pawn Код:

printf("You just earned %m. You now have a total of %m in your bank.", 12000, 554279811);
printf("%m", 1000000000);
printf("%m", 100000000);
printf("%m", 10000000);
printf("%m", 1000000);
printf("%m", 100000);
printf("%m", 10000);
printf("%m", 1000);
printf("%m", 100);
printf("%m", 10);
printf("%m", 1);
printf("%m", 0);

Output:

Код:

You just earned $12,000. You now have a total of $554,279,811 in your bank.
$1,000,000,000
$100,000,000
$10,000,000
$1,000,000
$100,000
$10,000
$1,000
$100
$10
$1
$0

Specifier code:

pawn Код:

// Money
FormatSpecifier<'m'>(output[], amount) {
    if (amount) {
        new
            i = 18,
            neg = amount < 0
        ;
        
        // The spaces must be there, otherwise strdel below won't work
        // on lower numbers.
        output = "$                ";
        
        // Null-out the end of it
        output[i] = 0;
        
        if (neg)
            amount = -amount;
        
        // Going right-left, add one number each time
        while (amount) {
            // Add a thousand separator every 3rd time
            if (!((i + 1) % 4))
                output[--i] = ',';
            
            // Now add the last digit of the number
            output[--i] = '0' + (amount % 10);
            
            // Then divide the number by 10, so digit in the end will be gone
            amount /= 10;
        }
        
        // Delete the spaces between the $-sign and the first (last) number
        strdel(output, 1, i);
        
        // Add a minus sign if needed
        if (neg)
            strins(output, "-", 1);
    } else {
        output = "$0";
    }
}
