How to turn off Vim relativenumber setting?

Question

Today I have discovered vim's relativenumber option. I really would like to use it, but sometimes I need to swap between relative numbering and classic one.

I have tried to turn it off with :set relativenumber=off option (which returns me error attached above) and using :set number again but none of those works.

Answer 1

To turn on relative line numbering use this:

:set rnu

To turn it off use this:

:set nornu
