WP-34S: # constant in exponent Message #1 Posted by Marcel Samek on 6 July 2013, 10:22 a.m. In debugging a program, I found that I had used: 1 EEX # nn It did not do what I expected. Is there a specific reason why # constants cannot be used for exponents, or did it just not make it into the design?

Re: WP-34S: # constant in exponent Message #3 Posted by Dieter on 6 July 2013, 1:20 p.m., in response to message #1 by Marcel Samek Marcel, the #nnn shortcut enters an integer and quits digit entry before and after the command. Thus it cannot be combined with regular digit entry. So the sequence... 1 EEX #123 ...does not return 1E123. Instead, it enters two different values: "1 EEX" equals 1 and #123 is, well, 123. So you will end up with 1 in Y and 123 in X. That's the way it is supposed to work. And it is consistent, since you cannot use... 1 #234 ...to enter 1234 either. Or even think of this one: #123 #456 Of course this will not produce a six-digit integer like 123456. ;-) By the way, your example can simply be coded as #001 SDR nn That's even shorter. Dieter

Re: WP-34S: # constant in exponent Message #4 Posted by Paul Dale on 6 July 2013, 8:33 p.m., in response to message #1 by Marcel Samek Dieter got it right. Consider EEX [pi]. What should this do? The # nnn commands are constants. They terminate command line input and raise the stack usually. The are not an extension of keyboard digit input. - Pauli
