RE: What's today's most accurate production retail calculator?
This question raised my interest and I have just checked this on the HP Prime.

First, this is the result you get in R (Angle Measure: Radians)
(The R Project for Statistical Computing):
Code:

> sprintf("%.16f",asin(acos(atan(tan(cos(sin(9)))))))
[1] "0.4247779607693797"

These are the results I get on the HP Prime:

Angle Measure: Radians
CAS:
0.424777960769

Home:
0.424777960769

Angle Measure: Degrees

CAS:
9.00000000591

Home:
8.99999864267


It is interesting to see that you get the same results in Radians mode but slightly different ones in Degrees mode.

All the best,
Dominik
