im cracking my brain on how to have a given value

(to eventually have an object spit out all the prime numbers)

Hi everybody,
im cracking my brain on how to have a given value
tested to see if it contains decimals
(to eventually have an object spit out all the prime numbers)
thanx in advance for any feedback.

You can use [% 1.] into [> 0.] to check for decimal values. Not 100% sure about the prime number thing.

There's probably many ways to find out prime numbers. here's my first thought about it :

Thanx alot for the reply's! (onfortunately im running 4.5, so guess i cannot run your patches)

here's the shortest way I've found to get the prime factorization of any number, using javascript. I wrote a similar one but then I found this on the forum and it's pretty much as streamlined as it gets. tests for all factors of 2, then goes to 3 and then adds 2 for each new test. so it won't try any other even numbers after that.

you can add a bit of code to say when an output number is prime or not, and collect them into a list of as many primes as you want.

function msg_int(v)
{
while (v%2==0)
{
outlet(0,2);
v/=2;
}
var i=3;
while (i*i
{
if (v%i==0)
{
v/=i;
outlet(0,i);
}
else i+=2;
}
if (v>1) outlet(0,v);
}


Object to test if given value has decimals?
