I went into their simulator and asked it for the square root of 2. Answer: 1.414214 (yup, just 6dp). Then I asked for the square of that: Ans^2. Answer: 2.00000

So it's not just that it's only displaying a small number of digits. Its actual working precision is really bad too.
For many applications it doesn't matter -- often just a few significant figures are more than enough. But I'd consider this level of inaccuracy to disqualify the calculator for serious use.
- Ecco 9y agoThis is a bug that's being currently worked on. See https://github.com/numworks/epsilon/issues/6 https://github.com/numworks/epsilon/issues/6
- gjm11 9y agoThat's good, I suppose, but the fact that anything like this was ever in there kinda suggests something fundamentally wrong in their approach. But I haven't looked at the actual code, and maybe I'm being too pessimistic.
