Cool! As underlying values, do you use integers, bigdecimals, or a decimalized double hack like in OpenHFT?

It uses BigDecimal. My first goal with the library was to provide a well-designed API. So to keep it simple for myself, I relied on BigDecimal for the calculations.

I think you are right, API is the most important part; internal implementation can be optimized later.

What is the double hack used in OpenHFT? I tried looking this up and came up short.

I’ll byte. Perhaps you didn’t look long enough. I’m sure the answer will float by at some point.

(see roundN)

Be careful and use it only if you know what you are doing and understand the limitations.
