My request for adding a n() method for rationals is an extension of a request I made earlier: On 7/10/07, Ted Kosan <[EMAIL PROTECTED]> wrote: >> I have found myself using numerical_approx() instead of RR() because >> it is also placed at the end of the line and so is relatively easy to >> locate the cursor there and add it.

You can try out a few by doing this: <snip> First, I would like to report that I have been using the .n() method fairly heavily since it was added to Sage and I find that it is able to be added to code and removed very quickly. I am currently using Sage for a Circuit Analysis class I am taking and I find that I am needing to take frequent 'peeks' at the numerical approximates of rational numbers. I have discovered that adding and removing N() for taking quick 'peeks' is not nearly as quick as adding and removing an n() method would be, and I miss this.
