Floating point values can be parsed with the
getFloat($value, array $options = array()) function. A floating
point value will be returned.
Example 554. Floating point value normalization
<?php
$locale = new Zend_Locale('de_AT');
$number = Zend_Locale_Format::getFloat('13.524,678',
array('precision' => 2,
'locale' => $locale)
);
// will return 13524.68
print $number;
