jquery - Javascript function to format currency -


i using below function generate formatted comma separated currency value in javascript not working scenarios:

1234 => 1,234 (correct) 1.03 => 1.3 (wrong)

how can fix issue in below function:

function formatthousands(n, dp) {     var s = '' + (math.floor(n)), d = n % 1, = s.length, r = '';     while ((i -= 3) > 0) {          r = ',' + s.substr(i, 3) + r;      }     return s.substr(0, + 3) + r + (d ? '.' + math.round(d * math.pow(10, dp || 2)) : ''); }

thanks in advance

to fix code need make sure rest has @ least digits "dp" parameter, if not add leading zeros.

function formatthousands(n, dp) {     var s = '' + (math.floor(n)), d = n % 1, = s.length, r = '';     while ((i -= 3) > 0) {          r = ',' + s.substr(i, 3) + r;      }     var rest = math.round(d * math.pow(10, dp || 2));     var rest_len = rest.tostring().length;     if(rest_len < dp) {         rest = '0'.repeat(dp - rest_len) + rest;     }     return s.substr(0, + 3) + r + (rest ? '.' + rest : ''); } console.log(formatthousands(1234.14, 2));       //1,234.14 console.log(formatthousands(1.003526, 4));      //1.0035

anyway find cleaner version of thousands separation others mentioned in comments.
