Hi, I'm trying to compare the numbers in a variable and return the two consecutive numbers with the greatest difference between them. e.g. 

my $file = '3.34, 3.67, 4.75, 4.98';

foreach my $number ($file)   {

  $number_counter++;
  $difference = $number - ($number - 1);
  

}

SO in this case the program wants to return 3.67, 4.75 and the difference between them (1.08). Obviously the above code didn't work. Does anyone have any ideas??
