Hello, I’ve a problem at js. How can I set the length of`Math.random`

?

# Set the length of random

Hey @eray6421 – can you tell me more about what you mean by “set the length”? `Math.random()`

will always return a value between 0 and 1 – are you interested in rounding that number to a lower precision (i.e., `0.692`

instead of `0.6918536114538683`

) or are you interested in generating a random number from with a range (such as randomly picking a number between 10 and 30, for example)? (Or have I misunderstood the question completely, haha?)

If you are looking to get something more than `0.5293852`

or `0.1488352`

etc. then just do the following!

```
let random = Math.random() * 100;
console.log(random) // Will output any number lower than 1000 and higher than 100.
```

If you want to get a random number from a to b just do `let x = Math.random()*Math.abs(a-b)+a`

Okay, I have found the answer. Thanks you.
