Full expression friendly calculator app? One of the apps I miss most from Linux when using a Mac is the Gnome calculator (gcalctool). I like that I can type out a full expression before evaluating it:



Is there a good free calculator app that works similarly or is there a way to install gcalctool?
gcalctool is available in MacPorts


Download and install MacPorts 
Perform the following action to install gcalctool from within a Terminal:

sudo port install gcalctool
