Load the package Miscellaneous`RealOnly` or better yet get the
SwitchableRealOnly package by Ted Ersek from MathSource at the WRI site.

Hi all,

With Mathematica, if I type


I get

0.5 + 0.866025 i

This is correct, of course, but I would like to get -1. instead. How do
I tell Mathematica that I want a real result (if there is one)?

Best regards,

Jose Carlos Santos
