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

//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? <!DOCTYPE html> <head> <title>Random</title> </head> <body> <script> var i=5,num=prompt("insert a number"); for(i<=100;i+=1;){ num=Math.random() document.write("num*i+<br>") } </script> </body> </html>
