I would like to format my numbers to always display 2 decimal places. lets say: I have a number => 21.268998 , the o/p I'm looking is to chop the rest of the decimal point and keep only the first 2 i.e:
21.26
however with the tofixed or toPrecision approach to always rounds to a certain decimal which is causing issues when a number is 99.999999, it rounds to 100.000 which is not right.
var num1 = "1";
document.getElementById('num1').innerHTML = (Math.round(num1 * 100) / 100).toFixed(2); // this is showing correctly
var num2 = "99.99999";
document.getElementById('num2').innerHTML = (Math.round(num2 * 100) / 100).toFixed(2);// this is incorrect=> I want to show 99.99
any idea how to get the first numbers to show always without rounding them off to the next number.
Jsfiidle:
You can use slice method in javascript:
var num2 = 99.99999;
num2 = num2.slice(0, (num2.indexOf("."))+3);
document.getElementById('num2').innerHTML = num2;
Here's an approach of a simple truncate, and not round off:
var number = 26.4363
var str = number.toString();
console.log(str.substring(0, str.indexOf(".")+3));Did u tried Math.trunc()?
var num = "99.99999";
var round=(Math.round(num * 100) / 100).toFixed(2)
var trunc=(Math.trunc(num * 100) / 100)
console.log(round);
console.log(trunc);
