Accepted answer

You can change it so it shows the data value instead by modifying your tooltip pointFormat from pointFormat: '{series.name}: <b>{point.percentage}%</b>', to pointFormat: '{series.name}: <b>{point.y}%</b>',

You can round the numbers by using the Highcharts.numberFormat() function like so in your formatter:

formatter: function() {
    return '<b>'+ this.point.name +'</b>: '+ Highcharts.numberFormat(this.percentage, 2) +' %';
}

Simplest approach to show the actual data values is to omit the formatter function. The tooltip will default to show the actual data.

Here is a detailed description about tooltip formatter http://api.highcharts.com/highcharts#tooltip.formatter

this.point (not shared) / this.points[i].point (shared)

And try this.points[i].point if this.point didn't work

You can use Format Strings to help you format numbers and dates.

// point.percentage = 29.9345816
pointFormat: '{point.percentage:.0f}%' // returns: `30%` - (rounds to nearest)
pointFormat: '{point.percentage:.1f}%' // returns: `29.9%`
pointFormat: '{point.percentage:.2f}%' // returns: `29.93%`
pointFormat: '{point.percentage:.3f}%' // returns: `29.935%`
