What are some examples of cases where using floating point IS appropriate that are less science-y and more business-y?

Specifically I'm looking for use cases for floating point which involve

* no trigonometry
* no calculus or differential equations
* no rotations (eg no graphics programming)
* no statistics

@b0rk I think it’s important to distinguish the “money scenario” that a lot of people use floats inadvertently wrong. The industry still has a lot of custom made systems that still use floats to make accountant calculations (difficult to explain to that developers they need to rewrite their 10 years system with a library to avoid this errors!)
