Rounding the distance to single number

Gmap give varchar 12.3 mi need 12 or 13 back

[cchapman09]

I'm using javascript to get the distance from Google maps. I get back 12.3 mi and I need it to display as 12 or 13. Is there a way to add this function to my code below.

<script type="text/javascript">
//<![CDATA[
google.load("maps", "2");
var gdir;
function load() {
if (GBrowserIsCompatible()) {
gdir = new google.maps.Directions();
google.maps.Event.addListener(gdir, "load", handleLoad);
gdir.load("from: '+&P8_FROMADDRESS.+' to: '+&P8_TOADDRESS.", {getSteps: true});
}
}
function handleLoad() {
document.getElementById("totalMiles").innerHTML = gdir.getDistance().html;
}
window.onload = load;
window.onunload = google.maps.Unload;
//]]>
</script>

Do you need to round it to the nearest whole number, or just strip the digits after the decimal point (where 15.99 would become 15)?

I would like to round it, but stripping the digits after the decimal point will be good.

welcome to WebmasterWorld [webmasterworld.com], cchapman09!

you could use the round() method of the Math object [w3schools.com]

[rocknbil]

Use Math.round() to int() to the nearest next integer, (down under .5, up at .5 or more,) Math.ceil() [w3schools.com] to int() up to the next integer, Math.floor() [w3schools.com] to round down.
