i3: Set a Floating Window Onto a Specific Positiion

This is the entry on my ~/.config/i3/config file that makes xcalc a floating window, and then places it on a specific place on the screen.

for_window [ title="SuperCalc" ] floating enable move right 930px,move down 870px

The window title ("SuperCalc" here) is provided by an entry on my ~/.Xresources file.
