to_decimals (locale_helper)

Formats a number using locale-aware NumberFormatter with configured decimal precision and currency/grouping symbols. Returns input unchanged if unset to avoid displaying empty values as zero.

function to_decimals($number, $decimals = NULL, $type=\NumberFormatter::DECIMAL)
{
	// ignore empty strings and return
	// NOTE: do not change it to empty otherwise tables will show a 0 with no decimal nor currency symbol
	if(!isset($number))
	{
		return $number;
	}

	$config = get_instance()->config;
	$fmt = new \NumberFormatter($config->item('number_locale'), $type);
	$fmt->setAttribute(\NumberFormatter::MIN_FRACTION_DIGITS, empty($decimals) ? DEFAULT_PRECISION : $config->item($decimals));
	$fmt->setAttribute(\NumberFormatter::MAX_FRACTION_DIGITS, empty($decimals) ? DEFAULT_PRECISION : $config->item($decimals));

	if(empty($config->item('thousands_separator')))
	{
		$fmt->setAttribute(\NumberFormatter::GROUPING_SEPARATOR_SYMBOL, '');
	}
	$fmt->setSymbol(\NumberFormatter::CURRENCY_SYMBOL,
