Percentage Difference

Hi guys, I've been doing trial and errors with my problem using the percentage formulas from this forum.

I need to know the percentage between the difference of two numbers.

To make it simple, for exmaple:

a1=100
b2=50
c2= i want to show that b2 is the 50% of a1, but i dont want c2 to be in percentage format. just general or number with no decimal.


i will be using this in something with higher values like

a1=5609
b2=5160.28 *i used a calc to deduct 8% from a1*
c2=here i want the value to be displayed as "8"

Thanks in advance. Will post too, if I manage to solve it myself.

thanks JieJenn for that and CheshireCat for the simplified formula.

let me clarify one thing though. i mistakenly wrote b2 and c2 and got myself confused, but figured it out.

it should be like this.

a1=100
b1=50
c1=(1-B1/A1)*100

THANKS!
