i want use javascript round number. since number currency, want round in these examples (2 decimal points):

  • 192.168 => 192.20
  • 192.11 => 192.20
  • 192.21 => 192.30
  • 192.26 => 192.30
  • 192.20 => 192.20

how achieve using javascript? built-in javascript function round number based on standard logic (less , more 5 round up).

// precision 10 10ths, 100 100ths, etc. function roundup(num, precision) {   return math.ceil(num * precision) / precision }  roundup(192.168, 10) //=> 192.2
