What is the JS equivalent to the PHP function number_format? - php

Question

PHP Function:
function formatNumberForDisplay($number, $decimal=0, $decimalSeperator='.', $numberSeperator=',')
{
return number_format($number, $decimal, $decimalSeperator, $numberSeperator);
}
Can anybody suggest to me the equivalent functionality in jQuery/JavaScript?

Answer 1

The same equivalent of number_format in js can found here
function number_format (number, decimals, dec_point, thousands_sep) {
// Strip all characters but numerical ones.
number = (number + '').replace(/[^0-9+\-Ee.]/g, '');
var n = !isFinite(+number) ? 0 : +number,
prec = !isFinite(+decimals) ? 0 : Math.abs(decimals),
sep = (typeof thousands_sep === 'undefined') ? ',' : thousands_sep,
dec = (typeof dec_point === 'undefined') ? '.' : dec_point,
s = '',
toFixedFix = function (n, prec) {
var k = Math.pow(10, prec);
return '' + Math.round(n * k) / k;
};
// Fix for IE parseFloat(0.55).toFixed(0) = 0;
s = (prec ? toFixedFix(n, prec) : '' + Math.round(n)).split('.');
if (s[0].length > 3) {
s[0] = s[0].replace(/\B(?=(?:\d{3})+(?!\d))/g, sep);
}
if ((s[1] || '').length < prec) {
s[1] = s[1] || '';
s[1] += new Array(prec - s[1].length + 1).join('0');
}
return s.join(dec);
}

Answer 2

Just use toLocaleString on an integer object.
https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/Number/toLocaleString#Browser_compatibility
let x = 1234567;
//if x is a string/non-number, use parseInt/parseFloat to convert to a number. Thanks #Aleksandr Kopelevich
x.toLocaleString('us', {minimumFractionDigits: 2, maximumFractionDigits: 2})

Answer 3

is this what you'd like to get?
yourFloatVarHere.toFixed(2);
voilà.

Answer 4

Native "Intl" object approach:
var amount = 5000.25;
var locale = 'de';
var options = {style: 'currency', currency: 'eur', minimumFractionDigits: 2, maximumFractionDigits: 2};
var formatter = new Intl.NumberFormat(locale, options);
console.log(formatter.format(amount));

Answer 5

I know it's an old thread, but I made my own function, which is in pure Javascript.
Simple Solution
https://gist.github.com/VassilisPallas/d73632e9de4794b7dd10b7408f7948e8/bf17eccef8521b4e5869bdc6a5b09a771356fbff
This works fine with finite numbers
function number_format(number, decimals, dec_point, thousands_point) {
if (number == null || !isFinite(number)) {
throw new TypeError("number is not valid");
}
if (!decimals) {
var len = number.toString().split('.').length;
decimals = len > 1 ? len : 0;
}
if (!dec_point) {
dec_point = '.';
}
if (!thousands_point) {
thousands_point = ',';
}
number = parseFloat(number).toFixed(decimals);
number = number.replace(".", dec_point);
var splitNum = number.split(dec_point);
splitNum[0] = splitNum[0].replace(/\B(?=(\d{3})+(?!\d))/g, thousands_point);
number = splitNum.join(dec_point);
return number;
}
Complex Solution
This solves the issue with big numbers
https://gist.github.com/VassilisPallas/d73632e9de4794b7dd10b7408f7948e8
const splitThousands = (number) => (dec_point, thousands_point) => {
const splitNum = number.toString().split(dec_point);
splitNum[0] = splitNum[0].replace(/\B(?=(\d{3})+(?!\d))/g, thousands_point);
return splitNum.join(dec_point);
};
const isBigNumber = (number) => number.toString().includes("e");
const isBigFloat = (number) => number.toString().includes("-");
const calcTrailing = (dec, len) => Number(dec) + 2 - len;
const handleBigFloats = (number, decimals) => {
if (!decimals) {
return "0";
}
const [numbers, dec] = number.toString().replace(".", "").split("e-");
const trailingZeros = calcTrailing(dec, numbers.length);
const res = `${"0.".padEnd(trailingZeros + 2, "0")}${numbers}`;
return decimals ? res.substring(0, 2) + res.substring(2, decimals + 2) : res;
};
const handleBigNumbers = (number, decimals, dec_point, thousands_point) => {
if (isBigFloat(number)) {
return handleBigFloats(number, decimals);
}
return splitThousands(BigInt(number))(dec_point, thousands_point);
};
function handleFiniteNumbers(number, decimals, dec_point, thousands_point) {
if (!isFinite(number)) {
throw new TypeError("number is not finite number");
}
if (!decimals) {
const len = number.toString().split(".").length;
decimals = len > 1 ? len : 0;
}
return splitThousands(
parseFloat(number).toFixed(decimals).replace(".", dec_point)
)(dec_point, thousands_point);
}
const numberFormat = (
number,
decimals,
dec_point = ".",
thousands_point = ","
) => {
if (number == null || typeof number !== "number") {
throw new TypeError("number is not valid");
}
if (isBigNumber(number)) {
return handleBigNumbers(number, decimals, dec_point, thousands_point);
}
return handleFiniteNumbers(number, decimals, dec_point, thousands_point);
};

Answer 6

Closer function to php number_format($number) should be number.toLocaleString('en') of javascript

Answer 7

Here is another short solution that should behaviour like the php-equivalent.
function number_format(number,decimals,dec_point,thousands_sep) {
number = number*1;//makes sure `number` is numeric value
var str = number.toFixed(decimals?decimals:0).toString().split('.');
var parts = [];
for ( var i=str[0].length; i>0; i-=3 ) {
parts.unshift(str[0].substring(Math.max(0,i-3),i));
}
str[0] = parts.join(thousands_sep?thousands_sep:',');
return str.join(dec_point?dec_point:'.');
}

Answer 8

Here is a simple function that you can use to achieve almost the same result of number_format in php:
function number_format(user_input){
var filtered_number = user_input.replace(/[^0-9]/gi, '');
var length = filtered_number.length;
var breakpoint = 1;
var formated_number = '';
for(i = 1; i <= length; i++){
if(breakpoint > 3){
breakpoint = 1;
formated_number = ',' + formated_number;
}
var next_letter = i + 1;
formated_number = filtered_number.substring(length - i, length - (i - 1)) + formated_number;
breakpoint++;
}
return formated_number;
}
Another way is to use ajax to make a call to a php script where you run number_format on the number and return it with ajax as a string. But it`s a bit messy.

Answer 9

It no easy, try to use simple jquery-plugins such as:
jquery-numberformatter
Jquery-Price-Format

Answer 10

My take on this:
var number_format = function(num) {
stringNum = num.toString();
stringNum = stringNum.split("");
c = 0;
if (stringNum.length>3) {
for (i=stringNum.length; i>-1; i--) {
if ( (c==3) && ((stringNum.length-i)!=stringNum.length) ) {
stringNum.splice(i, 0, ",");
c=0;
}
c++
}
return stringNum;
}
return num;
}
$("body").append(number_format(100000000));

Answer 11

Another variant of exposed examples:
const numberFormat = (value, decimals, decPoint, thousandsSep) => {
decPoint = decPoint || '.';
decimals = decimals !== undefined ? decimals : 2;
thousandsSep = thousandsSep || ' ';
if (typeof value === 'string') {
value = parseFloat(value);
}
let result = value.toLocaleString('en-US', {
maximumFractionDigits: decimals,
minimumFractionDigits: decimals
});
let pieces = result.split('.');
pieces[0] = pieces[0].split(',').join(thousandsSep);
return pieces.join(decPoint);
};

Answer 12

The JS equivalent will be:
var number = //input value
parseFloat(number).toFixed(3);

Answer 13

I'm to do it just calling the JS function as follows and it works:
var formattedNumber = number_format(value)
