It looks as if less than 10000 digits of Pi are stored in Mathematica, and others are calculated,

In[4]:= Timing[RealDigits[Pi, 10, 1, -1000]]

Out[4]= {8.94467*10^-19, {{9}, -999}}

In[5]:= Timing[RealDigits[Pi, 10, 1, -10000]]

Out[5]= {0.016, {{8}, -9999}}

The standard in programming way used in various programming languages including C and Python for finding the kth digit (from the end) of a non-negative integer x is

F:=(x,k)->iquo(x,10^(k-1)) mod 10;

For the last digit, with k=1, that reduces to x mod 10, and for the first digit, with k=length(x), that reduces to iquo(x,10^(length(x)-1)).

See also earlier thread.

I'd like to try, but I can't install 32-bit Maple in addition to 64-bit in Linux because of the licensing problem. I had only 2 licenses, and I used both of them - one for Linux, and one - for Windows.

Still, Classic looks and feels better.

Perhaps, I do it wrong. I just tried in the worksheet mode Tools-Options-Display. Changed Input display to Maple notation and tried to type abc_d. The input was black, italicized, and the d has appeared in the subscript.

Edit: Oh, I get it. I changed the Typesetting level to Maple Standard, and the results are much better. Still, it is hard to stand the ugly interface, but at least it is possible to type something.

I use Maple only for this site and Maple wiki posts, and if I want to post a plot, I do it in Standard - that's the only thing that I use it for. Since it is practically impossible to enter the commands in Standard, I type them in Classic and then copy and paste in Standard. Since 64-bit Linux doesn't have Classic, I don't use Maple in Linux - I am going to try the Dave Linder's trick tonight though to see if it works with Maple 12.

Anyway, I am sometimes wondering at myself - why I continue spending my (valuable) time on Maple - it's like an addiction. I'll try to stop doing that (are there any rehabs?)..

Both BarChart and ColumnGraph produced plots in my Maple 12.02, both in Classic and Standard, as

X := ["web" = 16, "philosophy" = 4, "document" = 9, 
"representation" = 47, "interactivity" = 4, "translation" = 15, 
"usability" = 11, "framework" = 7, "search" = 19, 
"communication" = 7, "maintenance" = 5, "education" = 9, 
"library" = 12, "process" = 20, "case-study" = 38, 
"practice" = 18, "markup" = 28, "extraction" = 22, 
"environment" = 9, "presentation" = 26, "publishing" = 3, 
"natural-language" = 8, "mechanized" = 30, 
"integrity" = 8, "organization" = 14];

Statistics:-BarChart(X);

Statistics:-ColumnGraph(X);

The results were not satisfactory though. Certainly, Excel or other statistics software would produce a better diagram.

Also, the ['interactive'] option worked neither in BarChart nor in ColumnGraph - a bug?

PS Frankly, people trying to use Maple for plotting always surprized me. I tried just now to name one program with worse plotting than Maple has, and I couldn't. -Alec

There is an undocumented kernelopts entry setsort,

kernelopts(setsort);
                                  1

However, it cannot be changed during a session,

kernelopts(setsort=0);
Error, kernelopts cannot set setsort value

Still, since it can be restored to the traditional set ordering using the commandline option --setsort=0, the changes are not that dramatic.
