Change it to :
use Scalar::Util qw( looks_like_number ); if( ! looks_like_number( $VAR1 ) ) { do something... }
If your definition of a number needs to be more restrictive than looks_like_number, let us know what we can do to help you refine the test further.
Scalar::Util is a core module; it comes with Perl as part of the standard distribution.
