Question: All I want to do is use the round function to display the Celsius temperature to one decimal point but I have no idea how to do this.

My code is as follows,

```
<?php
$fTemp = 0;
while ($fTemp <= 100) {
$cTemp = ($fTemp - 32) * .55;
echo $fTemp." Fahrenheit is equal to ".$cTemp." Celsius<br />"; 
$fTemp++;
}
?>

```

Any help would be greatly appreciated.

Answer: 
As in manual <http://www.php.net/manual/en/function.round.php>

```
$cTemp = round(($fTemp - 32) * .55 , 1);

```
You can use php [round](http://www.php.net/manual/en/function.round.php) function 

> 
> round($cTemp,1)
