Display Maximum 4 Digits?

[Warptweet]

Here is my code to display the rating of a game...

 

DAtabase connection stuff ehre... blah blah blah
echo "" . $row['upload_rating'] . "";
end the database stuff here... blah blah blah

 

But, sometimes the rating can be like 9.372783617863768541

 

How can I make it so that is the rating is like 9.15243 it only shows 9.152 (AKA, only display the first four integers?)

$rating = substr('$row[upload_rating]', 6);

You want to use either sprintf() or printf()

 

<?php
$x = 9.152437895656675;
printf("%01.3f",$x);
?>

Round() really can do it:

 

float round ( float $val [, int $precision] )

 

Returns the rounded value of val to specified precision (number of digits after the decimal point). precision can also be negative or zero (default).

If you are talking about calculations here, use round(), if talking about text, use substr().
