题目描述

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 $b$ .

输入格式

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.

输出格式

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