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 $1000$ 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 $5280$ (modern) feet. The Roman mile is believed to have been about $4854$ (modern) feet. Therefore a distance of $x$ English miles would correspond to $1000 \cdot \frac{5280}{4854}$ 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 $0 \le X \le 1000$ 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).
