$fmt = numfmt_create( 'de_DE', NumberFormatter::DECIMAL );
echo "Pattern: ".numfmt_get_pattern($fmt)."\n";
echo numfmt_format($fmt, 1234567.891234567890000)."\n";

echo "Pattern: ".$fmt->getPattern()."\n";
echo $fmt->format(1234567.891234567890000)."\n";
$fmt->setPattern("#0.# kg");
echo "Pattern: ".$fmt->getPattern()."\n";
echo $fmt->format(1234567.891234567890000)."\n";
