I have columns `RSL` and `SUMofRSL`. I have tried calculating the percentage but it returns either 100% or 0%. In some instances it is a wrong calculation since it shows 0% . Below are the examples for your reference.

```
RSL     SUMofRSL    Percentage
------------------------------
 2          2         100%
 1          2           0%
48         96           0%
10         10         100%

```

I have used 

```
([RSL] / [SumOfRSL]) * 100

```
