Rounding Up Product Pricing

Hi,

i was wondering, if it's available to prevent rounding up certain Product pricing, when a product is added to quote recod.

in this case i have the price there is 0,0049 EUR and when i try to save it rounds up to 0,00 EUR

Question: can i change the price field in the layout so that several decimal places are displayed for these products?
The totals are calculated correctly, but the display is misleading at this point

Example: support.sugarcrm.com/.../ (this is just a general setting, i only want this setting for certain products).

Thanks in advance!
