php - Custom Price Display Precision without Roundings in Magento -

on question member shivam helps me figure out problem custom price format...

how custom price format (with 3 precision) in magento

here use precision of 3

public function customformatprice($price, $includecontainer = true)    {           if ($this->getcurrentcurrency()) {           //sets floating point precision 4 points            return $this->getcurrentcurrency()->format($price, array('precision'=>3),     $includecontainer);           }            return $price;    } 

but used round precision of 4

public function roundprice($price,$roundto=4)  {  return round($price, $roundto);  } 

all works fine when use backend input price 9.2400 € output in frontend fine then. when input in backend 9.2450 € output on fronend roundet. seams miss somewhere round price right way.

this code use list view... (wrong display in roundings):

<?php echo  ''.mage::helper('checkout')->customformatprice($_minimalpricedisplayvalue /1.19 /$_bbase_qty, false) ?> 

this code use product view. (perfekt roundings) cants use code in list or price phtml.

<span class="price"><?php echo ''.mage::helper('checkout')->customformatprice(min($product_price)*1.19/($_bbase_qty),true,false); ?></span>`` 

hope can me figuring out problem in roundings or can me how can use last code in directly in list.phtml.

thanks help

open file [magento]\app\code\core\mage\core\model\store.php

    public function roundprice($price)     {         return round($price, 4);//change 2 4     }      public function customformatprice($price, $includecontainer = true, $options=array())     {         if ($this->getcurrentcurrency()) {             return $this->getcurrentcurrency()->format($price,$options, $includecontainer);         }         return $price;     }   echo mage::helper('checkout')->customformatprice(3000.12313,true,array('precision'=>4)); 

hope you
