You are in "complex" mode. simply do g CF 8 to clear flag 8--when 8 is on, complex mode is on. To turn on complex mode, you either do SF 8, or f (i) (I think the latter is correct---try it!) regards, Bill

 Re: HP 15 C - small typo, I guessMessage #4 Posted by Vieira, Luiz C. (Brazil) on 15 Nov 2003, 11:27 p.m.,in response to message #2 by bill platt Hi, Stefan and Bill; just a small remark over Bill's explanation: - [f][(i)] allows you to temporarily "see" the imaginary part of the complex number in the X-register; if the HP15C is not in complex mode, [f][(i)] returns an [ Error 3 ] message; - as Bill mentioned correctly, I consider [g][SF]8 as the most "natural" sequence to activate complex mode in the HP15C, because it does not change existing stack contents; [f][I] (upper case "I", beside (i) function in the keyboard) also activates complex mode, but this sequence alters stack contents; and the third possible sequence to activate complex mode in the HP15C is [f][Re<>Im] (real exchanges imaginary), that changes only X-register contents. Just my 2¢. Best regards. Luiz (Brazil)
