Answer 1

@Denis. The second answer has some problem,I change the code as follows:

// Animate the element's value from 0% to 110%:
jQuery({someValue: 0}).animate({someValue: 110}, {
    duration: 1000,
    easing:'swing', // can be anything
    step: function(now) { // called on every step
        // Update the element's text with rounded-up value:
        $('#el').text(Math.ceil(now) + "%");
    }
});

This will avoid the precision question.
