This question already has an answer here:
Over at Worldbuilding I posted this answer and included:
* Build a $1 Billion home ([Mukesh Ambani](https://en.wikipedia.org/wiki/Antilia_(building))) * Build a $1.2 Billion Yacht ([Roman Abramovich](https://en.wikipedia.org/wiki/Eclipse_(yacht)))
I got around that by using
USD instead of
$ and tested on Ask Ubuntu, Cooking and it seems to be limited to Worldbuilding, but obviously, I don't have an account everywhere...
