One useful feature of the `evalf` command is that it remembers previous results. But it also stores the current value of Digits as well as its input argument, to be associated with the remembered result.

There are two reasons for this. The fancier reason is so that, when Digits is reduced from that of an earlier successful computation, `evalf` can simply round off the earlier result to the desired number of decimal digits. The more basic reason is that `evalf` might...

In part due to a large number of requests on MaplePrimes, the command ?plottools,getdata was added to Maple 15. This new command gives programmers a better way to access the internals of plots and do things with the data they contain.

I was trying to come up with something really fun to do with this command, and another recent obsession came to mind: the game Minecraft.  Minecraft is nice, since like Maple it is written in Java and runs on lots of platforms!  For the uninitiated, Minecraft is a a sort of mostly unstructured "sandbox" game. The player starts in alone in a procedurally generated landscape consisting of blocks. They player can collect blocks with their hands or with tools and they use them to build new things. The wide array of things that people create in Minecraft is staggering.

So, I thought I would write some commands to export 3D plots in Maple to block structures in Minecraft.

I can no longer see answers to questions or added comments to posts.

I was able to view them last night. 

So there is a maximum number of conditions that one can set... good to know!

I tried your solution, and it does work. I'll just have to determine the values of my b1 and b2 parameters with a little programming.

Thank you very much!

In high school I was briefly fascinated by a triangular "jump all but one" game, commonly found at Cracker Barrel restaurants.  The basic premise is that any peg can "jump" over an adjacent peg to occupy the empty hole next to the jumped peg.  The jumped peg is then removed.  The goal is to continue jumping pegs until there is only one left.  

The instructions on the face of the Cracker Barrel version of this game say, "LEAVE ONLY ONE -- YOU'RE A GENIUS".  Wanting to claim the right to call myself a genius, unlike ordinary kids, who might just play the game a few times, I sat down on my Turbo-XT and started writing BASIC code.  The algorithm I came up with ran a bit slow, so I directed output to my printer and let it run over night.  In the morning the program was still chugging along.  I advanced the paper feed on the dot-matrix lineprinter -- the kind that used continuous feed paper with perforated edges and holes on each side.   Into view came 3 solutions represented by a string of numbers.   A quick check verified that I was now a genius.  

Now that Maple 15 is out, I thought I should share this little application I made: GoalTracker.mw. It is an application partially inspired by the BMI tracker in Nintendo's WiiFit application; you could easily use it to track a weight loss goal. But it could also be used to track other quantifiable goals. I am posting it here mostly because it takes advantage of two new features in Maple 15.

In the new Maple 15, if any calculation or process requires more than a few seconds, the cursor does not change to the hourglass (or equivalent) symbol. This makes it difficult to tell whether anything is happening and gives the impression that the program has hung.

I suggest that the hourglass (or equivalent) be resurrected whenever anything takes more than a few seconds.

The (new, Maple 15) Programming Guide is available for download from the Documentation Center.

This page from the Online Help suggests that GMP 4.2.1 is still being used in Maple 15.

But the latest "stable" release is GMP 4.3.2, see release notes here (various fixes and improvements in the 4.3.xx series mentioned).

Perhaps this could be updated in a service release Maple 15.xx.

What happened to all the Maple 5 applications at the maplesoft application center? 

Why just the other day I was looking at them.  Very dissappointed to see them "removed".  In particular a series of applications for mapping. 

The drop down option for Maple5 has dissappeared. 

Are they gone?  Can you put them back?

Since -1 = i^2 I thought that there could be some meaning behind "alternating" series that instead of beginning with (-1)^n begin with (a+b*i)^n, with real coefficients, for abs(a)<1 and abs(b)<1. I'm not sure but it seems that such series are absolutely convergent, because (a+b*i)^n -> 0+0I as n->infinity, hence the term utterly diminishing series instead of alternating series.

As an example,
Where sum((-1)^n*(n^(1/n)-1),n=1..infinity)= 0.187859642462067120248... ,

It still seems that the original post won't accept new replies, so I'm starting a new post.

On the topic of the quality of rendering of (2D) Math on websites, could that also be re-examined for both Mapleprimes and Maplesoft's on-line help system?

Right now the on-line help has pages with missing images in Examples. For example, the `int` and `sum` on-line help pages, here and here.

On that
