Javascript sets the amount style conversion to keep the two digit decimal sample code

 
//Conversion of amount format
function parsePrice(s) { 
var n = 2 //Sets the number of decimal places to be reserved
s = parseFloat((s + "").replace(/[^d.-]/g, "")).toFixed(n) + ""; 
var l = s.split(".")[0].split("").reverse(); 
var r = s.split(".")[1]; 
var t = ""; 
for (i = 0; i < l.length; i++) { 
t += l[i]; 
} 
return ' RMB ' + t.split("").reverse().join("") + "." + r; 
} 

Use:

 
var m=10; 
parsePrice(m);//Output:  RMB 10.00

var m=12.2 
parsePrice(m);//Output:  RMB 12.20

var m=12.31 
parsePrice(m);//Output:  RMB 12.31
