$fmt = numfmt_create( 'de_DE', NumberFormatter::DECIMAL );
echo "Digits: ".numfmt_get_attribute($fmt, NumberFormatter::MAX_FRACTION_DIGITS)."\n";

echo "Digits: ".$fmt->getAttribute(NumberFormatter::MAX_FRACTION_DIGITS)."\n";
echo $fmt->format(1234567.891234567890000)."\n";
$fmt->setAttribute(NumberFormatter::MAX_FRACTION_DIGITS, 2);
