Websitecode, currency, language (for sonician)

Problem:
get through code the current values for website, currency and language.
Hello,
Website:

//for name
Mage::app()->getWebsite()->getName();
//for code
Mage::app()->getWebsite()->getCode();

Currency:

Mage::app()->getStore()->getCurrentCurrencyCode();

Language:
This is a little tricky. You can get the ISO code for the language, because by standards French for France is different from French for Belgium

Mage::app()->getLocale()->getLocale();//will return something like fr_FR, fr_BE or en_US

if you want to go further and see only the language code it's simple

$isoCode = Mage::app()->getLocale()->getLocale();
$parts = explode("_", $isoCode);
$language = $parts[0];
$country = $parts[1];

Currency Rounding (for jjones17)

Problem:
Round the currency to the nearest ten ore (ten cents)

Possible solution:

Here is what you can try.
In lib/Zend/Currency.php, in the $_options member of the class change precision from 2 to 1.
This will have the desired effect but also side effects.
All the other currencies besides Norwegian Krone they will all be rounded in the same way.
All prices will look like this 123.4 instead of 123.40.
In order to avoid the first problem instead of changing the precision you can do a "quick and dirty" job.
in Mage_Directory_Model_Currency class for method formatTxt() add this right at the beginning.

if ($this->getCode() == 'NOK'){//if you need it for an other //currency just replace the code here
$options['precision'] = 1;
}

If you want to avoid the last problem (123.4 instead of 123.40) in the same method formatTxt() add add a 0 to the return value

return Mage::app()->getLocale()->currency($this->getCode())->toCurrency($price, $options)."0";

If you don't mind these 2 side effects than I recommended using the first solution. It's less code.
