If these lines:

   string currency = format("$%,.02f", 11_234_456.99);
   writeln(currency);

Will result in:

   $11,234,456.99

Why don't these lines:

   string notCurrency = format("%,", 11_234_456);
   writeln(notCurrency);

result in:

   11,234,456

???

Instead of a range violation?


Never mind. This works:

   string notCurrency = format("%,?d", ',', 11_234_456);
   writeln(notCurrency);
