This can be much more efficient:
<?php
function roundup ($value, $dp)
{
return ceil($value*pow(10, $dp))/pow(10, $dp);
}
function rounddown ($value, $dp)
{
return floor($value*pow(10, $dp))/pow(10, $dp);
}
?>
Much cleaner, isn't it ;)?

Unfortunately - it wasn't formatting the number right and you have to figure out which way you
want to go.
Using the code - I've come up with this:
<php
function fract_round($n, $dp)
{
if(round($n, $dp) > $n)
{
return number_format(ceil($n*pow(10, $dp))/pow(10,$dp),$dp);
}
else
{
return number_format(floor($n*pow(10,$dp))/pow(10,$dp),$dp);
}
}
?>
Of course we could just do this:
<?php
function fract_round($n, $dp)
{
return number_format(round($n, $dp), $dp);
}
?>
