How to use division in JavaScript
JavascriptDivisionJavascript Problem Overview
I want to divide a number in JavaScript and it would return a decimal value.
For example: 737/1070 - I want JavaScript to return 0.68; however it keeps rounding it off and return it as 0.
How do I set it to return me either two decimals place or the full results?
Javascript Solutions
Solution 1 - Javascript
Make one of those numbers a float.
737/parseFloat(1070)
or a bit faster:
737*1.0/1070
convert to 2 decimal places
Math.round(737 * 100.0 / 1070) / 100
Solution 2 - Javascript
(737/1070).toFixed(2); rounds the result to 2 decimals and returns it as a string. In this case the rounded result is 0.69 by the way, not 0.68. If you need a real float rounded to 2 decimals from your division, use parseFloat((737/1070).toFixed(2))
Solution 3 - Javascript
Also you can to use [.toPrecision(n)], where n is (total) the number of digits. So (23.467543).toPrecision(4) => 23.47 or (1241876.2341).toPrecision(8) => 1241876.2.
Solution 4 - Javascript
Try this
let ans = 737/1070;
console.log(ans.toFixed(2));
toFixed() function will do
Solution 5 - Javascript
to get it to 2 decimal places you can: alert( Math.round( 737 / 1070 * 100) / 100 )
Solution 6 - Javascript
with lodash:
const _ = require("lodash");
Use of _.divide() method
let gfg = _.divide(12, 5);
Printing the output
console.log(gfg)
