[SOLVED] Decimal

[unidox]

I have a string like 12354.134482058 and I only want it to show 12354.1, unless the .03 is 5+ then I need it to round up. How would I do this? Thanks

<?php
$n = 12354.156341234;
echo number_format($n, 1);
//12354.2
?>

 

I'm pretty sure $n can be a string too, i.e. quoted (it's a float in my example).
