One day Arif found a slide calipers. He eagerly wanted to know how this thing measures the value of a rectangular substance. Can you help Arif to find the Length of a rectangular substance?
The input file contains 2 numbers Main Scale Reading (M) and Vernier Super Imposition (V) (M<=100, V<=10) in mm.
Output will show a value rounded to 2 decimal places which is Length in a separate line.
