when I calc this value I got a big number like 48.4979898749,
how convert this to 48.49 ???
You could take the number and apply Number#toFixed with the wanted number of digits.
var valuee = document.getElementById("valueNum"),
result = document.getElementById("res");
valuee.onkeyup = function () {
"use strict";
result.innerHTML = "المبلغ المطلوب " + (valuee.value * 0.0680).toFixed(2) + " دولار";
};
<input type="text" id="valueNum">
<div id="res"></div>

I am try to solve a problem of LEETCODE using JavaScript, the problem is Multiply Strings and the solution is:
const string = (num) => {
return '' + num
}
var multiply = function(num1, num2) {
let result = string(num1*num2)
return result
};
console.log(multiply("123456789",
"987654321"))
it should return "121932631112635269"
but it returns 121932631112635260
Any Solution?
"123456789" * "987654321" should return "121932631112635269"
but it returns 121932631112635260

Closed 4 months ago.
we have string input number
input="6145390195186705543"
if we want to convert to number ;java Script auto rounded this input;
(6145390195186705543)
(6145390195186705000)
This should work for what you are trying to achieve
const myFunction = (num) => {
const length = num.length;
const result = `(${num.slice(0,16).padEnd(length, "0")})`;
return result;
};
const input="6145390195186705543";
const output = myFunction(input);
console.log(output)

var a = 8.4286;
var b = 2;
console.log(a-b)
Actual Output: 6.428599999999999
Expected Output: 6.4286
What is the reason behind this and how to get around it?
You can use .toFixed:
var a = 8.4286;
var b = 2;
let sub = a-b;
sub = sub.toFixed(4);
console.log(sub);

I am trying to receive a three-digit answer (example: 95.7, instead of 95.6923531)
You can use the javascript toFixed() method.
Example:
var x = 9.656;
x.toFixed(1); // returns 9.7
x.toFixed(2); // returns 9.66
x.toFixed(4); // returns 9.6560
x.toFixed(6); // returns 9.656000
Try this..
Syntax:
number.toFixed(x)
var num = 95.6923531;
console.log(num.toFixed(1));
console.log(num.toFixed(2));
console.log(num.toFixed(3));

How to format a number with commas as thousands separators?
(50 answers)
Closed 4 years ago.
const renderCommas = (number) => {
return number >= 1000 ? `${Number.parseFloat((number).toFixed(3))}` : number;
};
you can use toLocaleString()
a = 100000
console.log(a.toLocaleString());
You can use the following code to format a number with a comma:
var num = 100000;
var formatted = num.toLocaleString(undefined);
console.log(formatted);
