Question: I am using data from [this site](https://qrng.anu.edu.au/random-binary/) to get random numbers. They come in as a buffer, which I convert to binary, then into integer. I would like to finally convert those random numbers into decimal values between 0 and 1 like `Math.random()` produces.

For example, if I have the integer `151`, what do I need to do to make it look more like this float `0.0151234252525372`.

Here is my code:

```
    const bent = require('bent')
    const getBuffer = bent('buffer')

    let array = []
    async function random(){
        try{
            let result = await getBuffer("https://qrng.anu.edu.au/wp-content/plugins/colours-plugin/get_one_binary.php")
            let integer = parseInt(result.toString('utf8'), 2)
            let float = parseFloat(integer) // convert to a decimal between 0 and 1 like Math.random() produces
            array.push(float)
        }
        catch (error){return console.log(error)}
    }

    setInterval(()=>random().then(result => {
        console.log(array)
    }),50)

```

I'm not opposed to using the result of `Math.random()` to apply some math to the initial random number, but I'm just not sure what the right math would be.

Answer: 
You need to divide that random by max value - and max value for such generated bit sequence is `2^length(sequence)` (^ her denotes power, `**`, `Math.pow`).

For example, if current buffer is "01000100", you need to calculate

```
68/2^8 = 68/256 = 0.265625  

```
I am using math rather than programming as what @Mbo suggested. I haven't ran the code but fairly certain it will execute. More or less take the ((log of x)/x) and I did that on your float var.

```
const bent = require('bent')
    const getBuffer = bent('buffer')

    let array = []
    async function random(){
        try{
            let result = await getBuffer("https://qrng.anu.edu.au/wp-content/plugins/colours-plugin/get_one_binary.php")
            let integer = parseInt(result.toString('utf8'), 2)
            let float = (Math.log(integer)/integer) // convert to a decimal between 0 and 1 like Math.random() produces
            array.push(float)
        }
        catch (error){return console.log(error)}
    }

    setInterval(()=>random().then(result => {
        console.log(array)
    }),50)

```
