Why does "_" not give the last computed result?
I have a few calculations and want the numeric value of the last result in addition to the rational one given. I tried using N(_) but did not get the numeric of the last result but that of a one of the other results. I tried this for a few of the results and always get the same numeric result, the wrong one. Help.
You'll have to tell us exactly which platform you are on, which notebook or other thing ... thanks for all info!
Sorry. Using a .sagews within Sagemathcloud. I am running macOS Sierra with Safari. I read a question/answer on this site that stated to use "_" to use the last computed result, so I gave it a try, but no go.
