How much is $100 US in Aruba?

I'm curious, how would one convert $100 USD to the local currency in Aruba? I understand exchange rates can fluctuate, but is there a general rule of thumb or an approximate figure that I can use to get an idea of how much that would be in Aruban florins? It would be great if you could provide some insight into the process and any factors that might affect the conversion rate.
