number of decimal places - 2 vs 2.0

number of decimal places - 2 vs 2.0

When I choose the "sum" option for a Summary View the quantity is listed as:
1.0 or 4.0 when all I really want is a whole number (1 or 4). Is there a place to set the number of decimal places?

Also in Pivot view the qty line reads "Sum of ____" - can that be editted to read "Total" instead?

Thank you!
