The English word ``mile'' derives from the Latin ``mille passus'',
meaning ``a thousand paces''. A Roman mile was the distance a soldier
would walk in $1\,000$ paces (a pace being two steps, one with each foot).

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.


\section*{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.




\section*{Output}

Print an integer denoting the
closest number of Roman paces equivalent to X. Your answer should be
rounded to the closest integer.
