formatting output

[MrPantsTm]

So I have a calculation and it returns a long floating point number. It is only necessary to print out the first say 5 numbers of the mantissa something you could do with setprecision in C++. Does PHP have something to format the output? Thanks!

Did you look in the php manual on <

http://www.php.net/>?

Look at number_format() <

There's also sprintf():

<?
$a = 12345.123456789;

printf ('%.5f', $a);
?>

The script, when run outputs:

12345.12346

I did do a search for my question on php.net and I'm suprised I didn't come up with number_format. in any case, thanks to both of you, that's what I needed to know
