trimm up the decimal places in output

I have a perl script that reports the avg time of a application call and the total number of calls. This works fine, however I would like to trim the number of decimal places reported from 12 to like 3 and I don't know how.
Any suggestions? Here is what I use to get the avg time...

Code:
for $eRef ( @operationInfoArray ) {
        $avgTime = $eRef->{TIME}/$eRef->{COUNT};
        print "$eRef->{NAME} :           $avgTime :      $eRef->{COUNT}\n";

Result...........
GET_HIST : 193.529040881471 : 113719
OPEN_BATCH : 142.549565217391 : 575
CLOSE_BATCH : 164.506297229219 : 397


Thanks

Code:
$something = 123.123456789
$something = sprintf("%.3f", $something);

now something = 123.123

What actually your script will do? Is it calculate the average time taken for the execution of the script and number of times the script is called?

If so, i like to discuss regarding the script, find intresting and expecting one like that!

In 1936, Turing published his paper 'On Computable Numbers, with an Application to the Entscheidungsproblem'. In this paper, Turing reformulated Kurt Godel's 1931 results on the limits of proof and computation, replacing Godel's universal arithmetic-based formal language with the formal and simple hypothetical devices that became known as Turing machines.
