how to get rid of decimal point?

Hi,
I have input with decimal point ( 9.99 ) for hours variable hrs.
I need to change it to seconds.
Here is my code:
secs=`/usr/ucb/echo $hrs*3600 |bc`

But I don't want to see the decimal point.
I can use awk to trim it if there is one.

I am just wondering if there is better standard way to do it.

Thanks for your help!

echo '9.99*3600/1' | bc

OR

echo '9.99' | nawk '{printf("%d", $1 * 3600)}'

perl -e 'print ((shift)*3600)' $hr
