Sending data to paypal with no digits after the decimal point

[Mayfil]

Thank you for always helping me a lot.

I am developing my store with Magento ver. 1.9.1.0.

I got an error "PayPal gateway has rejected request.", when I test paypal function.

I asked Paypal support and they answered this error is because of wrong digits after the decimal point for our currency.

Which file should I fix to correct digits after the decimal point?

I found the solution by myself.

In the file, lib/Zend/Currency.php
change the following line

‘precision’ => 2,

to

‘precision’ => 0,

And in another file, app/code/core/Mage/Core/Model/Store.php
change the following line
return round($price, 2);
to
return round($price, 0);

By editing the files, I could send data to paypal with no digits after the decimal point.

Thank you for your attention.
