Errors in sub total.

[DrByte]

Any idea how to fix it?

v1.5.0.

mmm i can't wait for 1.5, maybe it's an easy mod
The single product price is ok, the problem is with sub-total.

[incircolo]

Why in administration, in whoisonline i can see a correct subtotal value, when the customer has products in cart, and in front-end the customer has an incorrect subtotal value ?
In which file is calculated the subtotal value for front-end and order ?

[DrByte]

There are many files involved in the order handling process.

All the rounding issues which you're talking about are fixed in v1.5

This kind of bug can give problems if the payment is PayPalEC ?
Does ZenCart pass incoherent data to PayPal?

[DrByte]

I think the word "incoherent" is inappropriate here, at least as far as Websters is concerned.

It passes whatever it calculates. So, if, as described earlier in this thread, you're using percent discounts or taxes that cause the calculations to result in a penny-difference with rounding, then that will have its impacts wherever those numbers are calculated. PayPal will read whatever is supplied to it. And, as far as PayPal goes, ZC attempts to ensure that any mismatch in line-item values is mitigated by taking fallback actions to submit less detailed information when necessary to allow the transaction to go through.

As I said, the rounding/calculation issues are fixed in the next version.

When a stable-production version of 1.5 is planned for ?
As you can imagine, the problem is now, but anyway the important thing is that at least there are no problems with PayPal transactions.

dear drbyte
I've found this on the forum that seems to fix the problem.

Is it possible?

this

  function zen_round($value, $precision) {
  $value = (int)$value + (round((ceil(round(($value - (int) $value)*pow(10, $precision), $precision)))/pow(10, $precision), $precision));
    return $value;
  } 

seems to work better than the original

  function zen_round($value, $precision) {
    $value =  round($value *pow(10,$precision),0);
    $value = $value/pow(10,$precision);
    return $value;
  } 

What do you think about it?
