Paypal "Suspected Fraud" Fix

[sreichel]

Hello,

since upgrading our shop to Mag. 1.9 we have some problems with paypal orders caused by rounding problems.

Found a working solution at https://www.kreativundsoehne.de/blog/magento-rundungsfehler-in-version-1-9-x.html

Would you includes this here to keep it update-safe? If "yes" i could also add an admin option to turn this on/off if desired.

Yep in 1931 there is still bug with paypal rounding related to
/app/code/core/Mage/Paypal/Model/Api/Nvp.php

I hope somebody could fix it finally, because above solution is old and not working
Thanks

@tomekjordan the above solution is definitly working for Paypal Standard. but you're right .... there is still a bug in Nvp.php (Paypal Express).

I'll try ...

I have this ugly / questionable fix for this running in production on a few stores. I say questionable because we 'force' an adjustment if we find that there's a small difference and ugly because the code was mostly done as emergency hotfixes during sale periods (when the issue would generally appear). From an accounting perspective, it's not ideal because it's not fixing the core of the issue, rather masking the underlying issue. Still, it's much better than constantly getting checkout issues. I doubt you will want a PR for it.. but let me know if you do.
