Using displayed rounded numbers in subsequent calcualtions

I have a work sheet that has a calcualtion where the result is displayed as a whole number with 1 decimal place. (4.25 becomes 4.3)

I want to perform a calculation that multiplioes the result (4.3). However, Excel seems to use the actual value before rounding. I want the result of 4.3*5 to be 21.5, not 21.3.

How do I get the formula to recognize the result (4.3) instead of the actual number (4.25) in susequent calculations?

Thank you VBA Noob
