Re: A problem of Conditions

If i have a condition in a program (for exemple a booleean : 1 if it's "yes") on A : for exemple if A>10 ,i =1 and else i=0. For boolean I would suggest using a flag instead of a variable : 38 CF 00 /* clear flag 00 39 RCL "Achar" 40 10 41 X<Y? 42 SF 00 /* set flag 00 Then you can easily test if th...

Re: [POLL] Compiler for DM15L ?

There is already a Python to RPN converter for the 42S, do you plan to do the same for the 15C?

Re: External stack

Ok, the WP 34S got local registers in 2011, Free42 got local variables now. Beyond the difference between registers and variables, is there anything else? Just for curiosity... AFAICS: On the plus side for the WP-34S: LocR is allocating local registers AND 16 local flags. There is so far no local f...

Re: External stack

This is cool ! I was wondering if LSTO would support storage arithmetic but it's not necessary: once you have created the local variable with LSTO you can just use the standard STO+, STO-, STO* and STO/ I have installed the Android apk on my tablet and I have an issue with the state file: the first ...

Re: Fundamental Mathematics

Interesting question, here is my take on this: arcsin(arccos(arctan(tan(cos(sin(9°))))) works as is only with non-typed arguments and results. Else I would say that it depends if the typing is strong or weak. So it’s a designer’s choice :) With strong typing, then arcsin(arccos(arctan(tan(cos(sin(9°...

Yes, it appears that the FAT disk was corrupted. After re-format there is no more issues.

Re: UPDATE: DMCP-3.13 / DM42-3.13

Just noticed one thing: if you move to the <Parent> directory from the PROGRAMS or STATE directories, then both of them are not listed and you cannot go back. That looks very strange. Would it be possible you can make disk image from your calc FAT? Something like dd if=/dev/sde of=dm42.fat and send...

Re: UPDATE: DMCP-3.13 / DM42-3.13

Perfect update with the combo file from 3.12. The new file management with directories, increased file items and two column display is really cool :) Just noticed one thing: if you move to the <Parent> directory from the PROGRAMS or STATE directories, then both of them are not listed and you cannot ...

Infinity is not a number and shouldn't be considered one.
This could the key for the initial issue reported by Walter. While the distributivity law is perfectly valid in ℂ, this may not be valid anymore if you try to apply it to infinity.
