Zend_Currency with PHP setLocale (de_DE) conflict #706

preparation

• set setlocale(LC_ALL, "de_DE.utf8");
• check if bcmath is installed on your server
• check if the german locale is installed on your server (de_DE.utf8), check this command via ssh: $ locale -a)

test

$currency = new \Zend_Currency('de_DE');
echo $currency->toCurrency(22, array('symbol' => 'EURO'));

instead of 22,00 you should see 220,00.

stacktrace

-> trigger \Zend_Currency::toCurrency()
--> triggers \Zend_Locale_Format::toNumber()
---> triggers \Zend_Locale_Math:: round()

Zend adds an .0 to a number.

---> triggers \Zend_Locale_Math:: normalize()

$convert = localeconv();
$value = str_replace($convert['thousands_sep'], "",(string) $value); 
//thousands_sep in de_DE is a .

so this replace transforms 70.0 into 700.
