RE: Free42 and cube root of complex number
The 1984 HP-71 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 HP-71, with the Math ROM, gives the same (correct) results: > (-8,0) ^ (1/3) (1,1.73205080757) > (-(8,0)) ^ (1/3) (1,-1.73205080757) J-F |
