You can also use:

$number=~ s/(\d*\.)(\d{0,3}).*/$1$2/;
No, that does not do any rounding off. If all you wanted to do was truncate the number of digits then substr() is better for that unless you had to search for the number in a string.

Generic, works in every language:
Code:
$number=int($number*1000)/1000;
