Help with Rounding Up - My first post

Hi all – My first post.

I am developing a simple web page form where the visitor can input height and width and the script calculates the area and price.

The script below does this fine.

However, I would like to roundup the answer to the next integer for example if price = 45.678 final output would be 46.

I have tried Math.round(x) but the syntax totally defeats me.

I would be grateful if someone would give me a hand and post the required change to my script below.

Hopefully not a big ask.

Regards

*<script type="text/javascript" language="Javascript">*

var h1 = 0;

var w2 = 0;

var price = 0;

function calculate () {

// The Calculation: change operator in this equation to change the calculation

price = h1 * w2 * .0005;

var elem;

elem = document.getElementById("h1");

elem.value = h1;

elem = document.getElementById("w2");

elem.value = w2;

elem = document.getElementById("price");

elem.value = price;

}

function setValue(elem) {

var val = 0.0;

if (elem.value != "") {

val = parseFloat(elem.value);

}

else {

val = 0.0;

}

switch (elem.id) {

case "h1": h1 = val; break;

case "w2": w2 = val; break;

}

calculate();

}

</script>
