roundTo(5, 11); // outputs 10
roundTo(6, 11); // outputs 12
roundTo(7, 11); // outputs 14
roundTo(8, 11); // outputs 8
roundTo(0.5, 3.7); // outputs 3.5
roundTo(0.5, 3.75); // outputs 4
roundTo(0.5, 3.8); // outputs 4

Describe alternatives you've considered

Additional context

function round_to_precision(x, precision) {
    var y = +x + (precision === undefined ? 0.5 : precision/2);
    return y - (y % (precision === undefined ? 1 : +precision));
}
