What method/ function shall I create to find the multiples of a random number from a range using for loop? F.ex var i=a i <b, I +=c

Math.round(Math.random())
but this gives only 0 and 1
do :
Math.round(Math.random()*(to-from)+from)

(I updated original answer, check it out....)

No, it'll give all multiples....

//Extending @Hatsy's answer
//use prompt() to let user decide
num = Math.random();
range = [prompt("from"),prompt("to")];
for (var stp = range[0]; stp <= range[1]; stp++) {
document.write(num*stp+"<br>");
//or alert
}
document.close();

Not good with JS syntax, so I'll just write the algorithm.
for (var i = 1; i < LIMIT; i++)
{
// print (rand_num * i)
}

It will give one number, wont it ? l' f like to have all the possible multiples between that range, like for 3 multiples 3,6,9 ,etc

The output is float numbers. How can I fix it?

for(i<=100;i+=1;){
num=Math.random()
document.write("num*i+<br>")
}
