PARI's commands

[science_man_88]

here's one that works both for the thread and has something else in common with Mersenne forums:

Yes, but the task is supposed to work with an arbitrary function. First, yours doesn't; second, it should really avoid such 'magic numbers'. What if, for example, the function took an hour to complete each run?

If you can code it, go right ahead. No one has so far in Pari/GP.

It's the directory part that has stumped me because all of ms-dos make directory commands apparently are internal only use grrrr.

longmultiply(a,b)= a=eval(a);b=eval(b);c=Vec(a);d=Vec(b);carry=0;answer=[];forstep(x=#d,1,[-1],if(d[x]==Vec("2"),print(yes)))

is my attempt at long multiplication.

why is this not complete lol, it only took ME less than 10 minutes to work out lol.

guess_the_number(N=10)= a=random(N);print("guess the number between 0 and "N);for(x=1,N,if(x>1,print("guess again"));b=input();if(b==a,break()));print("You gueesed it correctly")

Right. Also making it work cross-platform if possible: not using ~ in Windows, for example.

I don't understand the program; it seems to never use c, carry, or answer. Is this just incomplete?

I certainly wouldn't use eval() unless I absolutely had to.

I used eval so people could use powers not the full written number., and yes it's incomplete.

So post it to the site! (For copyright reasons, I probably shouldn't post it there myself.)

You should break it onto multiple lines if possible first; that way it will look nice.

the site isn't updating I added the guessing script, and the rate counter lol.
