So there is finally a game developper for CPLua
But this is not the good topic to discuss about that, we should return to the appropriate subject

I you need a translate, you can ask me... or Orwell : he speaks French very good!

It would be a real pity if a spoke English better than French

[PAP]

So here they are My Lua Programs
The comments are in French... Sorry!

There are some screenshots:

I don't need a translation, I can read french very well. But I cannot download your programs. Whenever I try, the modem hangs . Anyway, I can see the well-known Tower of Hanoi, the "classic" Breakout, and 3D pictures. I'm not interested on games, but I want to see your code organization. The algorithm for solving the Tower of Hanoi problem has some interest as well, since it is based on recursion.

If your native language is spanish, maybe you could help me to make a translation of KaosGenerator. I use Multi language support, but the only languages I know are French and English (and a bit German, but I don't know how to say "fractal" in German )

[betoe]

About the translation i would like to help, anyway i put it in another topic (Project: kaos Generator). If its french -> spanish, i really have several troubles with french, but lets talk about it firs. Cya.

Hi,
A nice function that stdlib must contain is something named for example BoldFont, that gets a text and returns that text written by variable letters.
ie It converts "Hello, World!" to "Hello, World!"
It is very useful for writing titles.
Thanks.

p.s Why there isn't a full documentation on the stdllib?

Like this? http://kilburn.free.fr/title.mcs

title(src,dest)
src is the string to convert.
dest is the name of the variable in which you want to put the converted string.

Example:

title("Hello World","title1")
Print title1

Nice, thanks... I don't want to make you disappointed but I think that we must let the others to use it. Because I no longer use CP-Basic, now I always use Lua.

fractal is just "Fraktal" in german
My mother tongue is german so i could help you a bit in translating your program into german

Yes, CP-Basic is rotten.

I don't want to make you disappointed but I think that we must let the others to use it.

What do you mean? Making a stdlib for Lua? Why not...

[Behnoud]

I have two different questions:
1- what do you do here, what is discussion about??
2- how I can learn Lua?
3- what is the most powerful programming language for CP?
3- what is the easiest programming language for CP?

[PAP]

1- what do you do here, what is discussion about??

This is an old effort to make CPBasic better by adding "standard" library functions. I expressed my opinion about such an effort about two years ago. I said then that CP Basic is very poor and extremely slow, so this effort was a nice try, but pointless; CPLua is so poor, so that there is no hope to make it useful by adding "library" functions written in CP Basic (in fact, you can't even define serious CP Basic functions, because the language itself is very very limited). Even after OS 3 release, nothing has been changed; CP Basic remains poor and extremely slow.
As you can see, all posts concerning CPBasic standard library are well aged. It seems that nobody is taking CPBasic seriously today, and I'm not surprised at all.

2- how I can learn Lua?

A question definitely . There are some manuals for Lua, you can find them in the CPLua topic, not here.

3- what is the most powerful programming language for CP?

Another question. Anyway, the answer is very short: CPLua, without a doubt.

3- what is the easiest programming language for CP?

It depends on what you mean by "easiest". Some people may not agree, but I think CPLua is easier to learn than CP Basic. Anyway, even if it's not, in practice you don't have a choice here.

Here's a suggestion for a rounding function that rounds up or down to a given number of decimal positions

round(x,n) = int(abs(x)*10^n+0.5)/10^n*signum(x)

where
x := the variable to round
n := number of decimal positions

--- EDIT ---
You might want to include a test for x=0, since signum(0) would return undefined..
A new function could look like this:

round(x,n) = piecewise(x,int(abs(x)*10^n+.5)/10^n*signum(x),x)

This is amazing.By the way, is it the same as the fround(x,n) or sround(x,n) commands?

[hellas1]

Hi all,

The previous post is cool!

I have the ClassPad 330 and it states that it gives decimals to Nth number when you choose a specific 0 to 9 decimal mode.

How do I access or use/install fround(x,n) & sround(x,n) and What are these commands used for?

Thanks a lot,
hellas1

[McCoy]

you can acces these on the soft keyboard(main -keyboard-cat.)or just by typing fround or sround.e.g to round up 2008.69 to one decimal place ,type fround(2008.69,1) EXE ans=2008.7

[hellas1]

Hi McCoy,

Thanks for the fround & sround info.

But...what about round(x,n)?

IS it the same as fround & sround?
hellas1

[McCoy]

No worries Hellas1. round(x,n)..mmm let's see. well i'm not sure if this command does exist on other calculators but i'm roughly certain that we don't have it on cp or not at least on cp 330.So i don't know whether it's the same or different from those.What I know is that when i want to round down/up certain number to a specific digits, i use fround(, and when i want to round up/down a number to whatever sig.figs i want , then i use sround(.
There're are cp experts here who can help you better though.
thank you.

[hellas1]

Hi McCoy,

Thanks for your insight.

No offense taken regarding the "bug" issue.
Just trying to help people who bought the CP 330 actually RELY on it.

I'll keep everyone posted.
hellas1

P.S. Anybody know about the round(x,n) command and if anyone can make it for the CP 300/330 IF it's superior to our fround & sround commands?

Thanks,
hellas1

Hello Everybody

I’m Portuguese Civil Engineering student and I’m having problems doing a interpolation, can any of you help me.



By the way do you know if there are program’s for Civil Engineering for CP
