adding a calculated column

[charles986]

I have noticed that when I have added a column to my data frame made up of 2 existing column divided by each other the NaN values in the data frame go, is this anotherway of getting rid of NaN values, or are they still there in the data frame

Can you provide an example? I don't understand what you mean by "the Nan values in the data frame go".
