  A scientific calculator that opens as a popup from your toolbar — or press Alt+S.                                                                                                                                          
                                                                                                                                                                                                                               Unlike most calculators, the entire expression stays visible and editable before you evaluate it. Type or tap to build something like sin(45) + sqrt(2) ^ 2, fix typos anywhere in the line, then press Enter or = to commit. The result is automatically copied to your clipboard.
