Display Currency with all decimals intact in AngularJS -

i need display currency format decimal places intact.

if value amount is: 123456.789 output should 1,23,456.789 $

if write {{amount | currency:$}} output is: 1,23,456.78 $ [removes last digit]

if write {{amount | currency:$:3}}, output is: 1,23,456.78 $ [it displays expected]

but problem can not fix number of decimals keeps changing.

got resolution. implemented following custom filter(currency symbol not mandatory :) )

myapp.filter('customnumber', function($filter) {     var standardnumfilterfn = $filter('number');     return function(num) {         if(num){             var numsplit = (''+num).split('.');             if(numsplit && numsplit[1]){                 return standardnumfilterfn(num, (''+numsplit[1]).length);             }             return standardnumfilterfn(num, 0);         }     }; }); 

and then:

{{amount | customnumber}}
