Im using javascript round to round the numbers. But when the value is $106.70 the output shows only $106.7 and its missing the last 0. How can I add a zero for numbers ending with a zero or is there any easier way than using if else to check this?

Reset to default 9

You can use the .toFixed method:

var n = 106.72; console.log(n.toFixed(2)); //=> '106.72'
var n = 106.70; console.log(n.toFixed(2)); //=> '106.70'
var n = 106.7; console.log(n.toFixed(2)); //=> '106.70'
var n = 106; console.log(n.toFixed(2)); //=> '106.00'

And it rounds:

var n = 106.76; console.log(n.toFixed(1)); //=> '106.8'
