Share 5 javascript numeric formatting Functions

Rounding in decimal format
These two sections of code help you round the list and show the price or order more useful for you:
Code 1:
Copy codeThe Code is as follows:
Function CurrencyFormatted (amount ){
Var I = parseFloat (amount );
If (isNaN (I) {I = 0.00 ;}
Var minus = '';
If (I <0) {minus = '-';}
I = Math. abs (I );
I = parseInt (I +. 005) * 100 );
I = I/100;
S = new String (I );
If (s. indexOf ('.') <0) {s + = '. 00 ';}
If (s. indexOf ('.') = (s. length-2) {s + = '0 ';}
S = minus + s;
Return s;
}
/**
* Usage: CurrencyFormatted (12345.678 );
* Result: 12345.68
**/

Code 2:
Copy codeThe Code is as follows:
Function format_number (pnumber, decimals ){
If (isNaN (pnumber) {return 0 };
If (pnumber = '') {return 0 };
Var snum = new String (pnumber );
Var sec = snum. split ('.');
Var whole = parseFloat (sec [0]);
Var result = '';
If (sec. length> 1 ){
Var dec = new String (sec [1]);
Dec = String (parseFloat (sec [1])/Math. pow (10, (dec. length-decimals )));
Dec = String (whole + Math. round (parseFloat (dec)/Math. pow (10, decimals ));
Var dot = dec. indexOf ('.');
If (dot =-1 ){
Dec + = '.';
Dot = dec. indexOf ('.');
}
While (dec. length <= dot + decimals) {dec + = '0 ';}
Result = dec;
} Else {
Var dot;
Var dec = new String (whole );
Dec + = '.';
Dot = dec. indexOf ('.');
While (dec. length <= dot + decimals) {dec + = '0 ';}
Result = dec;
}
Return result;
}
/**
* Usage: format_number (12345.678, 2 );
* Result: 12345.68
**/

Add comma
These two pieces of code help you add a comma to each three digits, which makes it easier to view large numbers.
Code 1:
Copy codeThe Code is as follows:
Function CommaFormatted (amount ){
Var delimiter = ","; // replace comma if desired
Amount = new String (amount );
Var a = amount. split ('.', 2)
Var d = a [1];
Var I = parseInt (a [0]);
If (isNaN (I) {return '';}
Var minus = '';
If (I <0) {minus = '-';}
I = Math. abs (I );
Var n = new String (I );
Var a = [];
While (n. length> 3)
{
Var nn = n. substr (n. length-3 );
A. unshift (nn );
N = n. substr (0, n. length-3 );
}
If (n. length> 0) {a. unshift (n );}
N = a. join (delimiter );
If (d. length <1) {amount = n ;}
Else {amount = n + '.' + d ;}
Amount = minus + amount;
Return amount;
}
/**
* Usage: CommaFormatted (12345678 );
* Result: 12,345,678
**/

Code 2:
Copy codeThe Code is as follows:
Function addCommas (nStr ){
NStr + = '';
Var x = nStr. split ('.');
Var x1 = x [0];
Var x2 = x. length>; 1? '.' + X [1]: '';
Var rgx =/(d +) (d {3 })/;
While (rgx. test (x1 )){
X1 = x1.replace (rgx, '$ 1' +', '+' $2 ');
}
Return x1 + x2;
}
/**
* Usage: addCommas (12345678 );
* Result: 12,345,678
**/

Number formatting, from PHP
This javascript code is designed with nubmer_format from PHP. Can be rounded to and separated by commas. In addition, you can customize the hexadecimal separation.
Copy codeThe Code is as follows:
Function number_format (number, decimals, dec_point, thousands_sep ){
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 );
}
/**
* Usage: number_format (123456.789, 2 ,'.',',');
* Result: 123,456.79
**/

Add an English sort suffix
Copy codeThe Code is as follows:
Number. prototype. toOrdinal = function (){
Var n = this %100;
Var suffix = ['th', 'st', 'nd', 'rd', 'th'];
Var ord = n <21? (N <4? Suffix [n]: suffix [0]): (n % 10> 4? Suffix [0]: suffix [n % 10]);
Return this + ord;
}
/*
* Usage:
* Var myNumOld = 23
* Var myNumNew = myNumOld. toOrdinal ()
* Result: 23rd
*/

Remove non-numeric characters
Copy codeThe Code is as follows:
Function stripNonNumeric (str)
{
Str + = '';
Var rgx =/^ d |. |-$ /;
Var out = '';
For (var I = 0; I <str. length; I ++)
{
If (rgx. test (str. charAt (I ))){
If (! (Str. charAt (I) = '.' & out. indexOf ('.')! =-1) |
(Str. charAt (I) = '-' & out. length! = 0 ))){
Out + = str. charAt (I );
}
}
}
Return out;
}
/*
* Usage: stripNonNumeric ('123et45dhs6. 6379 ');
* Result: 123456.789
*/
