Firmware 2021: Problem with exact polar form

[compsystems]

Hello

Flags: HOME view & RAD MODE (HAngle:=0) & (HComplex:=01).

HAngle:=0; HComplex:=01; [ENTER]

Example 1: ok

input: approx polar form
rectangular_coordinates( 4 ∡ 0.523598775598 ) [ENTER] [ 3.46410161514, 2 ] // OK. a+b*i > 3.46410161514 + 2*i

input: exact polar form
rectangular_coordinates( (4 ∡ (π/6)) ) [ENTER] [ 3.46410161514, 2 ] // OK

input: exact list form
rectangular_coordinates( [ 4, π/6 ] ) [ENTER] [ 3.46410161514, 2 ] // OK

input: approx list form
rectangular_coordinates( [ 4, 0.523598775598 ] ) [ENTER] [ 3.46410161514, 2 ] // OK

polar_coordinates( [ 3.46410161514, 2 ] ) [ENTER] [ 4, 0.523598775598 ] // OK



example 2: Problem

input: exact polar form
rectangular_coordinates( (√(2) ∡ (3*(π/4))) ) [ENTER] Error: Syntax Error Why?

input: approx polar form
rectangular_coordinates( 1.41421356237 ∡ 2.35619449019 ) [ENTER] [ −0.999999999995, 1 ] // OK
a+b*i > −0.999999999995 + i

input: exact list form
rectangular_coordinates( [ √(2) , (3*(π/4)) ] ) [ENTER] [ −0.999999999995, 1 ] // OK

input: approx list form
rectangular_coordinates( [ 1.41421356237, 2.35619449019 ] ) [ENTER] [ −0.999999999995, 1 ] // OK

polar_coordinates( [ −0.999999999995, 1 ] ) [ENTER] [1.41421356237,2.35619449019] // OK
