Grid values aren't rounded

The grid values should be rounded to avoid display like this:

$(".js-range-slider").ionRangeSlider({
    type: "double",
    skin: "round",
    grid: true,
    grid_num: 4,
    min: -39.90,
    max: 111.00,
    from: -39.90,
    to: 111.00
});

Same issue occurs when moving the slider:

Additional note: In this example the issue occurs for all values between -16 and 16. For all values outside this range the values (grid marks and current values) are rounded correctly.

Hi, this is how division works on computers :)
But you could fix precision using step attribute.
