in thread Why do i get an extra (duplicate) array element?-

Why not just use the numeric value in the string:

$ perl -demo DB<1> $A = "123" DB<2> if ( $A < 0 ) { print 'negative' }else {print 'non-negative'} non-negative DB<3> $A = "-123" DB<4> if ( $A < 0 ) { print 'negative' }else {print 'non-negative'} negative

As Occam said: Entia non sunt multiplicanda praeter necessitatem.
