Here are some steps for generating a non-integer random number that is not in the format of 1.2321312312

I am looking to create random numbers that are not integers, for example 2.45, 2.69, 4.52, with a maximum of two decimal places.

Currently, the generated number includes many decimal places like 2.213123123123 but I would like it to be displayed as 2.21.

Additionally, when clicking on another button, it reverts back to the previous value instead of generating a new one.

var button = document.createElement("button");
button.innerHTML = "Click";
button.onclick = function myFunction() {
    var input = document.getElementsByClassName("has-input")[1];
    input.value = Math.random(Math.random() * 100) + 2;
}

document.getElementsByClassName("place_bet m_t_30 bbb manual_bet_select")[0].appendChild(button);

Furthermore, upon clicking the "btn btn_green" button (on the site), it resets to the old value.

Answer №1

Utilizing the toFixed function in JavaScript allows for specific decimal place precision when converting numbers to strings.

(Math.random() * 10).toFixed(3)
"6.578"

Answer №2

//In this code snippet, we are generating random numbers in different ways
let num1 =  Math.floor(Math.random() * 10) + (Math.floor(Math.random() * 100)/100)
console.log(num1)
//Here, we are using 'toFixed()' method to fix the decimal places
let num2 = (Math.random() + (Math.random() * 10)).toFixed(2)
console.log(num2)
