### Problem Statement

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

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

### Constraints

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

### Input

Input is given from Standard Input in the following format:

D


### Output

Print the answer. Your output will be considered correct when its absolute or relative error from our answer is at most 10^{-3}.

### Sample Input 1

1000


### Sample Output 1

10


The water pressure at a depth of 1000 meters is 10 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
