I have some products where the customer wish to order quantity in decimal. like 1.2 meter.

I have sett the quantity in ADMIN to use 1 decimal.
and in the product sett minimum qty= 0.1 and qty Units to 0.1.

The problem is, the default qty shows 0.1 but i want that it shold show 1.0 as default.
The next problem is that the QTY units shows below the qty box.
How do i remove this.
