You are given a positive decimal number x.

Your task is to convert it to the "simple exponential notation".

Let x = a·10^{b}, where 1 ≤ a < 10, then in general case the "simple exponential notation" looks like "aEb". If b equals to zero, the part "Eb" should be skipped. If a is an integer, it should be written without decimal point. Also there should not be extra zeroes in a and b.


-----Input-----

The only line contains the positive decimal number x. The length of the line will not exceed 10^6. Note that you are given too large number, so you can't use standard built-in data types "float", "double" and other.


-----Output-----

Print the only line — the "simple exponential notation" of the given number x.


-----Examples-----
