The value of a measurement can be output using getValue().
Example 595. Output a value
<?php
$locale = new Zend_Locale('de');
$mystring = "1.234.567,89";
$unit = new Zend_Measure_Length($mystring,
Zend_Measure_Length::STANDARD,
$locale);
echo $unit->getValue();
The getValue() method accepts an optional parameter
round which allows to define a precision for the generated
output. The standard precision is '2'.
