Hello, users and developer group of the famous hp prime calculator
Sorry for my technical english.

Bugs report

*1
V1(X,Y) := (X²/3 - Y²/5 = 1); [enter] returns (X,Y)->(((X^2/3)-(Y^2/5))==1) // error
(X,Y)->(((X^2/3)-(Y^2/5))=1) // ok
right(V1) [Enter] returns 0 // (0 synonymous of false), error because although (((X^2/3)-(Y^2/5))==1 is false, this should not be compared, it must be interpreted as equation (X,Y)->(((X^2/3)-(Y^2/5))=1)

I do not use x in lowercase because the internal user variable V1 requires it [SYMB KEY], I also want to perform analytical [CAS], graphical [PLOT KEY] and numeric analyzes [NUM KEY] using the same definition.

*2
The following list of operations of terms, for the case of e*x^0 this closing the simulator, I do not know if this also happens in the physical calculator

e^(2*π*i)*y, √(-4), e*x^0, e*x₁*x₂, a₂*b₂*c₂*x²,-4*pi


*3

[[0,0],[0,1],[1,0],[1,1]] [enter]
evalb(Ans) [enter] returns evalb(Ans) ?
[[false,false],
[false,true],
[true,false],
[true,true]] // ok

*4
[[0 OR 0],
[0 OR 1],
[1 OR 0],
[1 OR 1]]

[enter] returns

[[false],
[true],
[1],
[1]]

sometimes true others 1 ?

*5
[[0 AND 0],
[0 AND 1],
[1 AND 0],
[1 AND 1]]
[enter] returns
[[0],[0],[false],[true]]

Thank you
