Inspect a Float with 17 Decimal Places

Version: Phuoc Hung OJ Extended

Problem Statement

A real input is parsed as a Python 3 float. Its stored binary value may differ slightly from the ideal decimal input. Display the stored value using fixed-point notation with exactly 17 digits after the decimal point. Do not apply round() before formatting.

Input

The only line contains a real number $x$, parsed as Python 3 float.

Output

Print one line containing $x$ with exactly 17 digits after the decimal point, including trailing zeros.

Subtasks

• Subtask 1 (100 points): $|x|\le 10^6$; $x$ is finite.

Examples

Example 1

Input

0.1

Output

0.10000000000000001

Explanation. The decimal value $0.1$ has no exact finite binary representation; formatting the stored float to 17 decimal places gives 0.10000000000000001.

Example 2

Input

0.5

Output

0.50000000000000000

Explanation. The value $0.5=1/2$ is exactly representable in binary; .17f pads trailing zeros to produce 0.50000000000000000.

Example 3

Input

0.3

Output

0.29999999999999999

Explanation. The stored binary approximation of $0.3$ is slightly below the ideal decimal value; 17-decimal formatting gives 0.29999999999999999.
