The currency used in the popular "Sims" series of computer games by Maxis / Electronic Arts.
The § symbol is used to define the currency. The § symbol appears in place of $ when typed within the game when using a standard keyboard.
A simolean is presumably made up of 100 'somethings' but I do not believe that the fraction has ever been given a name. Simcent or Simolette perhaps?
That pink flamingo is worth §7 if you buy them in bulk.
Woohoo I just got §564 for a large supreme pizza.
