[abc231_a]Water Pressure

Problem Statement

Let us assume that water pressure depends only on depth and is dfracx100\\dfrac{x}{100} megapascal at a depth of xx meters.

What is the water pressure in megapascals at a depth of DD meters?

Constraints

  • 1leqDleq100001 \\leq D \\leq 10000
  • DD is an integer.

Input

Input is given from Standard Input in the following format:

DD

Output

Print the answer. Your output will be considered correct when its absolute or relative error from our answer is at most 10310^{-3}.


Sample Input 1

1000

Sample Output 1

10

The water pressure at a depth of 10001000 meters is 1010 megapascal. Outputs such as 10.0 and 9.999999 would also be accepted.


Sample Input 2

50

Sample Output 2

0.5

Sample Input 3

3141

Sample Output 3

31.41
