We need the ability to keep track of fractional units of inventory. For example 1.20 instead of 1 or 2. Given the nature of our business it is nearly impossible for us to keep track of a large segment of our inventory. Also, having the ability to calculate cost beyond 2 decimal places will help us a great deal on POs. For ex. we often get quoted a price like 1.4354 for supplies. When the PO is for several thousand not allowing for exact pricing largely throws the totals off.
