# Roaming Romans

Over time, the actual distance referred to as a “mile” has changed. The modern English mile is $5\, 280$ (modern) feet. The Roman mile is believed to have been about $4\, 854$ (modern) feet. Therefore a distance of $x$ English miles would correspond to $1\, 000 \cdot \frac{5\, 280}{4\, 854}$ Roman paces.

Write a program to convert distances in English miles into Roman paces.

## Input

Input will consist of a single line containing a single real number $0 \le X \le 1\, 000$ denoting a distance in English miles. The number $X$ has at most $3$ digits of precision after the decimal point.

## Output

Print an integer denoting the closest number of Roman paces equivalent to X. Your answer should be rounded to the closest integer (with an exact $.5$ decimal part rounded up).
