Time: 1 s · Memory: 256 MB

Statement

An angle is given in degrees: $d$ . Convert it to radians:

$r = \frac{d \cdot \pi}{180}$

A single integer $d$ ( $0 \le d \le 360$ ).

A single number — $r$ with exactly 4 digits after the decimal point (for example, 3.1416).

Input

Output

3.1416

Input

Output

1.5708

Use the language constant for $\pi$ : Python — math.pi, C++ — M_PI, Go — math.Pi. In this problem the answer has 4 digits: .4f, %.4f.
