# How To Set Number Format Using Jquery

Here is a step:

1. Create one HTML form or You can use your own form
```<form class="form-wrap" action="" method="post">
<input type="number" class="number-formate-input">
<input type="button" value="Convert" class="number-formate-btn">
<p class="number-formate-output"></p>
</form>```
```jQuery( document ).ready( function( \$ ) {
\$( '.number-formate-btn' ).on( 'click', function(){
var number_val = \$( '.number-formate-input' ).val();
var custom_number_format_op = custom_number_format( number_val, '2', );
\$( '.number-formate-output' ).text( 'Output: ' + custom_number_format_op );
\$( '.number-formate-input' ).val( '' );
} );
});

function custom_number_format( number_input, decimals, dec_point, thousands_sep ) {
var number 			= ( number_input + '' ).replace( /[^0-9+\-Ee.]/g, '' );
var finite_number 	= !isFinite( +number ) ? 0 : +number;
var finite_decimals = !isFinite( +decimals ) ? 0 : Math.abs( decimals );
var seperater 		= ( typeof thousands_sep === 'undefined' ) ? ',' : thousands_sep;
var decimal_pont 	= ( typeof dec_point === 'undefined' ) ? '.' : dec_point;
var number_output 	= '';
var toFixedFix = function ( n, prec ) {
if( ( '' + n ).indexOf( 'e' ) === -1 ) {
return +( Math.round( n + 'e+' + prec ) + 'e-' + prec );
} else {
var arr = ( '' + n ).split( 'e' );
let sig = '';
if ( +arr[1] + prec > 0 ) {
sig = '+';
}
return ( +(Math.round( +arr[0] + 'e' + sig + ( +arr[1] + prec ) ) + 'e-' + prec ) ).toFixed( prec );
}
}
number_output = ( finite_decimals ? toFixedFix( finite_number, finite_decimals ).toString() : '' + Math.round( finite_number ) ).split( '.' );
if( number_output[0].length > 3 ) {
number_output[0] = number_output[0].replace( /\B(?=(?:\d{3})+(?!\d))/g, seperater );
}
if( ( number_output[1] || '' ).length < finite_decimals ) {
number_output[1] = number_output[1] || '';
number_output[1] += new Array( finite_decimals - number_output[1].length + 1 ).join( '0' );
}
return number_output.join( decimal_pont );
}```
