Forensics? Have these calculators committed a crime (against numerical analysis)?

I think it's forensic in the sense that, should you perform this operation on an unknown calculator, this chart could be used to identify it.

On second thought what you'd probably do is identify the chipset of a calculator.

I think you'd identify the "OS" of a calculator. For example, HP famously had lots of long, complex, highly accurate algorithms in its firmware. They could reuse large portions of that between different models, regardless of the hardware executing it.

		For sure. I was imagining that the software would be pretty thin and the FP behavior would be primarily a function of chipset, but I stand corrected.

If they have, this site has their fingerprints.

Failure to identify an identity! Straight to calculator jail!

This is a good way to find out what fugitive chip an unknown calculator is harboring.
