round up to 10

[jwk811]

i forgot how to do this, but i need to make sure it rounds only up and to the 10

[corbin]

function roundtotens($num) {
if($num % 10) {
}
else {
$mod = $num % 10;
$add = 10 - $mod;
$num += $add;
$num = round($num);
if($num % 10) {
$num -= 1;
}
}
return $num;
}

thanks, nothing any simpler?

try the ceil() function

 

<?php

echo ceil(9.123423);

// Value would be 10

?>

yeah that was it! thanks! edit: actually that just goes up one integar

[jwk811]

function roundtotens($num) {
if($num % 10) {
}
else {
$mod = $num % 10;
$add = 10 - $mod;
$num += $add;
$num = round($num);
if($num % 10) {
$num -= 1;
}
}
return $num;
}

 

if that rounds up to 10 how can i make it round down to 10 instead?

I dont think that function works.

Im pretty sure these do..

 

<?php

$num = 123;

function round_up_ten($num)
{
$mod = $num % 10;
$add = 10 - $mod;
$num += $add;
echo $num;
}

function round_dwn_ten($num)
{
$mod = $num % 10;
$add = 10 - (10 - $mod);
$num -= $add;
echo $num;
}

round_up_ten($num); // Should be 130
round_dwn_ten($num); // Should be 120
?>
