myRandomNumber = Math.random()\*49+1;
Does this do it?

why don’t you use Math.ceil? 😉
```auto
var ranNumber = Math.ceil(Math.random()*50);
```

[AS]var ranNum = math.floor(math.random)\*50+1[/AS]
senocular explained why to use math.floor in a thread somewhere in best of kirupa but I’m too lazy to find it now:P

yeah… i know that.
and your script is totally wrong…
```auto
var ranNum = Math.floor(Math.random()*50)+1;
```

oops… i’m embarrased now:x
anyway… I normally use just the random function… sure, it’s deprecated, but it works for normal purposes and I find writing code a lot easier. It’s what I used in my footer.

Was mine actually wrong, just out of interest? :nerd:

Because you need to round it.

I use this function
Math.randomBetween = function(a, b) {
return (a+Math.floor(Math.random()\*(b-a+1)));
};
I cant remember where i found it, but it works for me.
just do
your\_random\_number = Math.randomBetween(1,50);
