————————

Scientific counting is a convenient method used by scientists to represent large or small numbers. It satisfies the regular expression [+ -] [1-9] [0-9] + E [+ -] [0-9] +, that is, the integer part of the number has only one digit, and the decimal part has at least one digit. Even if the sign of the number and its exponential part is positive, it must be clearly given.

Now the real number a is given in the format of scientific counting method. Please write a program to output a according to the ordinary digital representation, and ensure that all significant bits are reserved.

### Input format:

Each input contains one test case, that is, a real number a represented by scientific counting method. The storage length of this number shall not exceed 9999 bytes, and the absolute value of its exponent shall not exceed 9999.

### Output format:

For each test case, output a in one line according to the ordinary digital representation, and ensure that all significant bits are reserved, including 0 at the end.
