Here is an excerpt of the data that I need to be transformed:
| Current | What I need |
| 22.10399999999999 | 22.1040 |
| 22.1092.11 | 22.1092.11 |
| 22.1040.10 | 22.1040.10 |
| 22.2014999999998 | 22.2015 |
| FH10202020 | FH10202020 |
| 022100210FSB | 022100210FSB |
I need to round the first set of decimals to 4 places. The data is currently in string format because I will lose the data with the letters, if I convert to double
