wp34s Adding decimals to fractions  Norman Dziedzic  05022011 On the 32sii and 35s I can be in fraction mode and type something like
On the wp34s the same keystrokes don't add anything. Entering an integer works but it seems that as soon as I type the first decimal separator, it wants to see the second one as well.
Re: wp34s Adding decimals to fractions  Walter B  05022011 Hi Norman, Thanks, you found another bug!

Re: wp34s Adding decimals to fractions  Paul Dale  05022011 You are in fraction mode. 0.125 is 0 / 125 which is plain zero.
What would you expect if you added 1.125 ? Where does fraction mode end and real mode being is the question here.
Re: wp34s Adding decimals to fractions  Gene Wright  05022011 Hey Pauli.
I think the assumption is that the 32sII paradigm for fractions is "the way things should work".
Re: wp34s Adding decimals to fractions  Paul Dale  05022011 Even if it is inconsistent?
I don't have a 32sII to hand so I can't experiment at the moment. The problem might be that we're not changing the display during entry in fraction mode so it isn't clear enough what is happening.
Re: wp34s Adding decimals to fractions  Norman Dziedzic  05022011 Quote:Gene is right. I was going by the 32sii standard. To enter 0/125 on the 32sii you would enter . 0 . 125 The operative part of enter a fraction is that decimal occurs twice in the entry. With only a single . the entry is considered a decimal entry. The 32sii gives the example of entering 5/8 as either . 5 . 8 OR 5 . . 8

Re: wp34s Adding decimals to fractions  Paul Dale  05022011 I understand the difference now. Shows how often I use fraction mode on the 32sII :)

Quote:That's inconsistent. By plain and simple logic, 5/8 shall be entered as .5.8  5..8 enters 5 0/8 ! Re: wp34s Adding decimals to fractions  Norman Dziedzic  05032011 Quote:For better or worse, it is consistent with the 32sII manual ;) Perhaps the developers of the 32sII realized that there is virtually no need to ever key in a fraction with numerator of 0. HOWEVER, this input method which I'm choosing to call a short cut does not work on the 35s. (Yes I know it is technically not a short cut since it is the same number of keystrokes as . 5 . 8 but it is easier to key in because of the repeated .). Working on a my 32sII with FDISP on.

I guess the major question is whether or not the 32SII should be followed exactly or not. If you want to duplicate the 32SII then I highly recommend reading chapter 5 of the 32SII manual which is on the Museum DVDs.
Re: wp34s Adding decimals to fractions  Walter B  05032011 We don't follow the 32SII exactly  you will never see anything like 0 5/8 on the wp34s I hope ;)
When PROFRC is set, the logic behind our input is: .5.8 ENTER results in 5/8with the 0/1 indicating you're in fraction mode. One may discuss whether the 0/1 is necessary or should be discarded, since the missing decimal mark may be sufficient evidence.

Re: wp34s Adding decimals to fractions  Marcus von Cube, Germany  05032011 The decimal mark is missing in most cases, so we need some indication.
Re: wp34s Adding decimals to fractions (now in)  Walter B  05062011 Hi Norman, all, FYI, the latest build (820) handles all such inputs and operations properly, as far as I checked. Enjoy  and continue testing :) !
