Hi @lisaash,
You could use the Recode Data in a Column option to extract segment, or use column formula :
- Settings to extract the value :

Or formula :
Word( [1 5], :Value, "", Unmatched( :Value ) )
- Settings to extract the sign at the end :

Or formula :
Word( -1, :Value, "", Unmatched( :Value ) )
If your values may have a different format/length, I think a Regex may be a more flexible option.
Please find attached the datatable used for the demonstration, containing the formula described above in the "Value extracted" and "Sign extracted" columns.
Hope this answer will help you,
