Question

I cannot get the round() function to work correctly. Here’s what I’m currently doing:

if ($con2 == "sf") {
    $formula = $num * 0.00694444;
    $formula = round($formula);
    $result = $num . $si . "<br>RESULT: " . $formula . $sf;
};

With this code, when $num is 144, the result is 0.99999936. However, I need that to be rounded to 1. Why is this happening and how can I get round() to behave the way I expect it to instead of this counter-intuitive way?

Answer 1

Okay – so could you try this script and see what happens, this is working the with behaviour you’re looking for when I enter 144:

<?
if($_POST){
    $num=$_POST["number"];
    $formula = $num * 0.00694444;
    $formula = round($formula);
    echo $formula;
} else {
?>
<form action="test.php" method="post">
<input type="text" name="number" />
<input type="submit" />
</form>
<?
}
?>
