Showing two decimal places on a number with 0 or 1 decimals

[adam0101]

How can I get the following numbers:
2
2.3
2.45
2.456

To appear as:
2.00
2.30
2.45
2.46

If I try to use "round(num,2)", the output is incorrect:
2
2.3
2.45
2.46

Thanks

printf or sprintf should work.

printf("%.2f", $val);
$string = sprintf("%.2f", $val);

//Daniel

Thank you,
After posting this, I searched the forum and found out about the number_format() function as well. Next time I'll search the forum first.
