Incorrectly calculated integral.
Hello
There is an elliptic integral EllipticF[80*Pi/180,(2+Sqrt[3])/4] whose correct result is: 2.1338951423213... (according to Wolfram Alpha).
On the other hand, HP-Prime CAS Mode after pressing Shift+Enter gets the results as in the attached image.
In the former action, the amplitude = 80.*π/180 (with a dot).
In the second = = 80*π/180 (without the dot).
The results are decidedly different: 2.13... vs. 7.96...
Hence my question is it just like that with me or is it a bug?
Could someone check this.
Greetings.
PS.
Firmware 2.1.14730 (2023 04 13).
After the purge(x) command it is the same.
