RE: Free42 and cube root of complex number
The 1984 HP71 was supporting the signed zero, but it was sometimes a source of confusion for users and the signed zero was not kept in later machines (starting with the 28C).
So yes, the HP71, with the Math ROM, gives the same (correct) results: > (8,0) ^ (1/3) (1,1.73205080757) > ((8,0)) ^ (1/3) (1,1.73205080757) JF
