I received this error message when I mutiply two large values and displaying the resultant output.

Is there any other altenative way to go with too large values?

Version of unix and size of the numbers would help.

Try "bc" which is a front end to "dc".

Code:
result=`echo "1048576 * 1048576"|bc`

echo $result
1099511627776
