Is it possible to determine an integer from a string? Like and int($x) function? I know this is normal in strongly typed languages like C, but obviously it is different with Perl's situational data typing. I'm inserting values into a database and DB2 simply will not accept '2' as an integer, I must insert it as 2. So I need a way to check if some variable is an integer. Here is some context: 
$table = 'sometable';
$col1 = 'id';
$col2 = 'name;
$val1 = 3;
$val2 = 'somename';
&insert($table, $col1, $col2, $val1, $val2);

The insert function uses the values to build an SQL query string.
