sc_format_num() not handling internationalization

I am seeing the sc_format_num() is no different to PHP number_format. I would suggest to implement the sc_format_num or adding another macro that using PHP NumberFormatter.

My code example,


$sql = "SELECT SUM(quantity * unitPrice) FROM purchase_detail WHERE purchaseFk = {id}";
sc_lookup(dataset, $sql);

$total = 0;

if(!empty({dataset[0][0]})) {
	$total = {dataset[0][0]};
}

$num = new NumberFormatter(sc_get_regional(), NumberFormatter::DECIMAL);
{total} = $num->format($total);

By using NumberFormatter, we also handle the internationalization when formatting our number. I understand that NumberFormatter is only available for PHP 5.3 and above. This may cause the compatibility issue. Nevertheles, I expect the sc_format_num() to handle the internationalization since one of the main point in using scriptcase is internationalization.
