Defines how numeric values are formatted and displayed,
depending on the culture. Numeric values are formatted using
standard or custom patterns stored in the properties of a
NumberFormatInfo.
This class contains information, such as currency, decimal
separators, and other numeric symbols.
To create a NumberFormatInfo for a specific culture,
create a CultureInfo for that culture and retrieve the
CultureInfo->NumberFormat property. Or use
NumberFormatInfo::getInstance($culture).
To create a NumberFormatInfo for the invariant culture, use the
InvariantInfo::getInvariantInfo().
function testLocalizedPatterns()
{
$fr = NumberFormatInfo::getInstance('fr');
$de = NumberFormatInfo::getInstance('de');
$en = NumberFormatInfo::getInstance('en_US');
$this->assertEquals($fr->DecimalSeparator, ',');
$this->assertEquals($de->DecimalSeparator, ',');
$this->assertEquals($en->DecimalSeparator, '.');
$this->assertEquals($fr->GroupSeparator, ' ');
$this->assertEquals($de->GroupSeparator, '.');
$this->assertEquals($en->GroupSeparator, ',');
}
