>>52485487
All useful programs are I/O. Yes.
And all useful Functional programs ultimately provide I/O, just with a different conceptualisation of how to represent I/O in the codebase.
>>52485498
It's a function of an I/O of X to an I/O of Y. It is up to the external environment to "perform" those I/O actions.
FP is shit
there is no inherent advantage to FP and FP users are needlessly smug about using it
Imperative programming makes gains when it finds a way to restrict programs (i.e. letting compilers do certain optimizations or safety checks).
Functional programming makes gains when it finds a way to express more programs (i.e. letting programmers work with new effects).
>>52485550
The biggest advantage is when doing highly parallel programming because immutable and thus shareable data.
Also side-effect-free code is far most testable.
It's not like a magic replacement that does things imperative CAN'T do. It just does almost everything better. I say almost because there are a few inherently imperative algorithms, but they are FEW and far between.
>>52485578
yeah right
for games at the very least most algorithms are inherently imperative
>>52485601

I give zero fucks, those are not critical systems and they don't matter.
>>52485608

>>52485516
>unless the compiler is super clever you're doing a lot of needless data copying
The compiler doesn't need to be super clever to do this when you have linearity.
You're pointing out Haskell's flaws as if they're somehow inherent flaws of FP. Which is something a lot of anti-FP people seem to do. There are lots of horrible, horrible imperative languages but you don't see people talking about Brainfuck as if it somehow reflects on everything else.
>>52485601
Games are basically just state to state functions (not the entire state at once, all the time, mind you), which can be optimized to be mutation with linearity, plus rendering. Which on the application side is just building lists of commands and writing shaders, which are best expressed as pure functions anyways (plus specific effects like image load/store).

any possible benefits of FP get wiped away as soon as you wrap too much state as input.

>>52485774

you're wrapping pretty much the entire program's state as an input just so you can say that it doesn't have state. it's unnecessary. it's obvious that the game loop would have access to the game's state, it doesn't need to be a function parameter everywhere.

>it doesn't need to be a function parameter everywhere
It isn't a parameter everywhere. It's a parameter at the top level, and then it gets split up when "smaller" subfunctions are called at many levels.
Even in imperative languages, it's good to package up the state into a big structure (and have the update be a state->state function) because of things like fixed timestep with interpolation, delta encoding for networking, buffering between the game thread and render thread, etc.
>>52485815
It's not a bad language, but it's not a good example of the power of functional programming, at least not any more. Forced laziness everywhere is bad for reasoning about performance, and its type system is a bunch of features tacked together haphazardly ending up with "system F-omega modulo everything but dependent types or linearity".

>>52485782
periods or exclamation marks would make sense for terminating statements. historically (before C), semicolons were not for _terminating_ statements, but for continuing to the next one. ALGOL-likes usually used syntax roughly equivalent to the following:BEGIN
DO_FIRST_THING;
DO_SECOND_THING;
DO_FINAL_THING
END
notice that the final thing has no semicolon, since it is the result of the block. this is more similar to the semicolon's use in human language than what C-like languages use it for.
>>52485737
yeah, my experience working with Idris brings me closer to feeling that it's just trying to clean up Haskell's act, but it's not really creating something totally new. the feeling of programming in Idris is very similar to programming in Haskell, but even if i'm not fully taking advantage of the type system it feels a lot cleaner.
I'm really interested in trying out your language when the time comes because I think you're one of the few people that is interested in making a good general-purpose dependently typed language that isn't just a slightly modified version of Haskell.

There was a function for determining prime numbers.

int i=2;
while(i<=x-1){
if (x %% i != 0) {
return true;
}
else {
i++;
}
return false;
}
for the while statement, wouldn't it be more efficient to do while (i<=x/2) ? because given you are searching for a prime number, there exists no divisor greater half the dividend for a prime number? or am i just crazy and stupid here?

KILL YOURSELF TARD
Stopping Pong in CHIP-8 because I don't like the way I've written conditionals and the way I've repeated lines because I'm ignoring subroutines, as well as touching up my assembler to accommodate labels.
I think I know a way to go about fitting Nokia Snake in chip-8's 4kb ram. Instead of having a byte to store the x and y positions of each node, I just store the relative position of each node using 2 bits. The first is 1 if down, the second is 1 if right, so 10 is down and left. To fill the 2048 pixel screen would only take half the ram, 1/8 if I were to fit 4 2-bits in each byte.
As for drawing, should just be a simple matter of drawing onto the tail to cancel it out and then drawing on the new head, rather than re-drawing everything.
It's going to be a fun project lads

Ah thanks for that, it would be 4 bits then (even if you could squeeze it into 3 bits, I'm not hardcore enough). So assuming up-down-left-right, dead-right would be 0001. I will have to take great care in making sure 11xx or xx11 never happens, but at least now I can fit all my nodes in half a byte rather than 2 bytes (or1.5 bytes if I squeezed it more)

You can't read the screen, and storing the positions of nodes was the original issue using up too much RAM. Even if you were to draw on top of each tile to see if it sets the collision flag, it would not work if a snake node was adjacent to 3 different snake nodes.

If I set it like 00-up, 01-down, 10-left, 11-right, I can do a shift right, and the remaining bit would determine if it's horizontal or vertical and the carry bit would determine if it's going towards upper-left or lower-right

So does anyone else agree with me about the problem?
>>52487733
mnemonics are usually shit the concepts should just stick in your brain with your own mental model of how it works if you aren't retarded
>>52487740
what problem?

It is a custom, division before multiplication is how we do it. There's no "mathematical truth" to one way or the other, it's just a matter of syntax and convention.
One of the reasons we do it this way is because of how it looks when it's actually written. We don't write 1 / 2 we write ½.
>>52487746
Apparently you can't read. This is the important part

>>52487765
So, to detractors, does
½ * 2 equal 1, or 1/4?
>>52487765
>It is a custom
No, it's just incorrect. Being retarded isn't a reason to continue being retarded.
>>52487765
god damnit you fucking tard
if it's written like this:1
____
5*5
you do 5*5 first so it's 1/(5*5)
½*(4*4) is the same as (1/2)*(4*4) so in that case you do divide first

Calm down faggot
>>52487778
FUCK FUCK FUCKING RETARD I'LL RAPE YOU IN THE ASS
MULTIPLICATION AND DIVISION HAVE EQUAL PRECEDENCE AND IT GOES LEFT TO RIGHT SO OF COURSE IT'S 1 YOU FUCKING RETARD IT HAS NOTHING TO DO WITH 1/2 VS ½
PLUG IT INTO GOOGLE AND THERE'S YOUR ANSWER
20 5 / 2 2 * *
there
perfectly unambiguous
ONLY A FUCKING SPERG WOULD RATHER LEARN A STUPID FUCKING WORD THAN ACTUALLY UNDERSTAND THE MATH CONCEPT SO YOU DON'T HAVE TO "DECRYPT" THE MNEMONIC EVERY TIME BEFORE YOU USE IT
To all the fags arguing over this
Left to right same precedence
and
division before multiplication
ARE THE SAME THING AND ALWAYS HAVE THE SAME RESULTS

Addition: A + B
Subtraction: A - B
Multiplication: A x B
Division: A / B
Exponentiation: A ^ B
Logarithm: Log B of A
Root: Root B of A
Why are these backwards?
Why don't they get symbols?
>>52487954
Logs and roots are functions.
>>52487980
>British Education
>>52487954
Root B of A can be represented as A**(1/B) in some languages. So in that regard it does have a symbol.

That's gay
>>52487997
same as A^(1/B)
and logx and ln are kinda symbols too just not a single character in length
>>52487980
also this
>>52487997
But why do you have to say (1/B)
Why does the written version go
B (radical) A
>>52487980
Everything is functions. What's your point?
>>52488024
nigga this is basic math
2^2=4
2^1=2
2^0.5=sqrt(2)
2^0=1
2^-1=1/2
2^-2=1/4
>>52488047
I know that shit you absolute fucking retarded cunt
You apparently don't fucking realise there's a goddamn symbol called the radical fucking symbol, I guess it's too fucking radical and cool for you you stupid autistic piece of shit
a√b = b^(1/a)
holy
fucking
shit
what i'm asking you, you son of a bitch, is why the symbol is fucking backwards and why there isn't one for logarithms
thanks
>>52488063
WHAT THE FUCK YOU FUCKING TARD
of course i know the radical fucking symbol
how is the symbol "backwards", what the fuck?
log, ln works perfectly fine
shit gettin real bois
>>52488063
>a√b = b^(1/a)
no it doesn't, a√b = √a*a*b
>>52488074
>>52488063
Anons stop, we're getting worried
>>52488090
he's talking about the ath root, not a*sqrt(b)

>division before multiplication
Only if the identity rule applies.
>>52488105
You just answered your own question as to why there's no operators for sqrt or log. It gets convoluted really quickly when you try to shoehorn every operator into a character set. Just include the basic arithmetic as single character operators and use sqrt(), log(), for more complicated operations.

You could argue that / should be implemented as a function and not as an operator. Too bad for you the ASCII character set is already established and '/' was included.
your education sucks apparently or you're dumb as shit
these get special symbols:

I don't see any reason to want dynamic typing other than "I am lazy and don't want to cast all the time" or "I am an artist and my variables should be as abstract as my paintings, casting detracts from my artistic direction"
