No, i dont think so...

I compile functions to ints...

Unlike CPLua, it's a basic-like language (asm-like) so it's lower level than CPLua

@vanhoa and Orwell:

I guess both languages are compiled to bytecode and executed by a bytecode interpreter.

Don't you think that the queen-bench is a more accurate way to find out the speed of these languages vs. CP-Basic?

CPBasic IS defeated by default!

[Xerxes]

I expect nothing else.

Sold? Hmm... now that you think about about it...

Noooooo!

No, nothing has been abandonned nor sold.

Yeeeeees!

and on top of that I had to look for my futur job (which I found now, yay ).

I'm sure it has to do with programming, otherwise I have a feeling that you will find your job to be boooring.

IMHO you shouldn't write benchmarks based on call to the language libraries. Do some tests with simple programs like

a  = {}
for i = 1,100000 do a[i] = i*i end

to see the real speed of the interpreter itself

Even better, a true test must include real world benchmark programs. For example, I could write a LNA function in OWBasic and run it to see the difference in speed. However, I don't have time for such things right now. Programs for solving problems such as the "eight queens" or the "knight tour" could also be used as benchmarks as well.
Anyway, differences in pixel-drawing programs don't prove anything, unless someone is interested on graphics only.

CPBasic IS defeated by default!

Indeed. We could also look at any dictionary:
masochist (noun): a person who prefers CPBasic instead of CPLua or any other ClassPad programming language; synonym of CPBasicist.

I expect nothing else.

Of course you should expect such an answer .

@PAP:
Sure, but speed is relative and so its also good to know the "slowness" of CP-Basic. I will try to add the benchmarking results of these languages to have more clarity.

[The_AFX_Master]

this is pointless Xerxes, isn't about two o three functions, is about anything. CPLua is 10+ times faster than basic and doing benchmarking to proof that is a time loss

[Xerxes]

Ok, I understand. I have no experience with the CP-300+, but I am going to buy one to learn more about this interesting calculator.

[The_AFX_Master]

then you can made the benchmarks and post them on your database

Hello everybody,I've had a competion "Mathematic Olympic 30-4", it's a large comp in my contry. And now i'm back, i will continue the linking soft.

WOW, i've found an interesting function wink2.gif

PLAY mel$,dur%,vol%

Plays a melody coded in mel. The characters have the following meaning.
Character Meaning
'a'..'h' Play the corresponding note
'#' Increment next note a half step (cis, dis..)
'+' Change to next higher octave
'-' Change to next lower octave
1 Select whole notes 1/1
2 Select half notes 1/2
4 Select quarter notes 1/4
8 Select eighth notes 1/8
6 Select sixteenth notes 1/16
' ' or 'p' Play a rest
'r' Reset to default value

The parameter dur controls the duration (in milliseconds) of the sound. The parameter vol controls the volume or waveform of the signal. The value 100 is the highest volume.

example: PLAY "4ee2e4ee2e4egcd2e4ffffeeeeedde2dg",1400,100

enjoy wink2.gif

What are numerical values at the end for? What happens if you change them, do they change the song or something? Also what are the mel dur and vol things for?

What are numerical values at the end for? What happens if you change them, do they change the song or something? Also what are the mel dur and vol things for?

dur%:controls the duration (in milliseconds) of the sound
vol%:the volume or waveform of the signal (0-100)

Compare your self:
dur%=500 and dur%=5000.
vol%=10 and vol%=100.

[kevinator9]

I am not sure where to put this in the file.
i Have.

! Test Song
PLAY "4ee2e4ee2e4egcd2ep4fffffeeeedde2dcg", 1400, 100

Where do I put the volume bit? And how EXACTLY do I insert it? Also what do the numbers

, 1400, 100

do?

[vanhoa]

In that case, dur%=1400 and vol%=100

[kevinator9]

Oh! Thankyou for explaining!
Also you mentioned on MSN that you could put .wma files on it... Is that really possible, if so how?

[TomL_12953]

It cannot be a real compilation, it's just a tokenizing operation. CPLua does the same thing

Why can't it be a real compilation? Is there some reason source code can't be compiled to machine language?
