How do you round to 1 decimal place in Javascript?

Question

Can you round a number in javascript to 1 character after the decimal point (properly rounded)?

I tried the *10, round, /10 but it leaves two decimals at the end of

Answer 1

Little Angular filter if anyone wants it:

angular.module('filters').filter('decimalPlace', function() {
    return function(num, precision) {
        var multiplier = Math.pow(10, precision || 0);
        return Math.round(num * multiplier) / multiplier;
    };
});

use if via:

{{model.value| decimalPlace}}
{{model.value| decimalPlace:1}}
{{model.value| decimalPlace:2}}
