How about other roots? How to get cube root, for example? The ^ command gives powers; with the inverse flag, I ^, you will get the roots. So, for example, to find the cube root of 27, you can enter 27 RET 3 I ^ > few years ago i asked for how to do square root in comp.emacs and was > having a fit to boot, and they told me raise it to 1/2. Someone may well have said that, but it was also pointed out that the manual (under "Basic Arithmetic") clearly states that "Q" gives the square root.
