When working with currencies they you probably also have to handle precision. Most currencies use a precision of 2. This means that when you have 100 US dollars you could also have 50 cents. The related value is simply a floating value.
<?php
$currency = new Zend_Currency(
array(
'value' => 1000.50,
'currency' => 'USD',
)
);
print $currency; // Could return '$ 1.000,50'
Of course, as the default precision is 2, you will get '00' for the decimal value when there is no precision to display.
<?php
$currency = new Zend_Currency(
array(
'value' => 1000,
'currency' => 'USD',
)
);
print $currency; // Could return '$ 1.000,00'
To get rid of this default precision you could simply use the precision option and set it to '0'. And you can set any other precision you want to use between 0 and 9. All values will be rounded or streched when they don't fit the set precision.
<?php
$currency = new Zend_Currency(
array(
'value' => 1000,30,
'currency' => 'USD',
'precision' => 0
)
);
print $currency; // Could return '$ 1.000'
