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

31.41
