Scientific notation is a convenient way for scientists to represent large or small numbers, satisfying regular expressions [+-][1-9]. " [0-9]+e[+-][0-9]+, that is, the integer portion of the number is only 1 bits, and the fractional part has at least 1 digits, and the sign of the number and its exponential portion is definitely given even for positive numbers.

The real number A is given in the format of the scientific notation, and the program is programmed to output a in normal numeric notation and to ensure that all valid bits are preserved.

Input format:

Each input contains 1 test cases, a real number a in scientific notation. The number is stored for no more than 9999 bytes and the absolute value of its exponent does not exceed 9999.

Output format:

For each test case, output a in a line of normal numeric notation and ensure that all valid bits are retained, including the end of 0.

Input Sample 1:

+1.23400E-03

Output Example 1:

0.00123400

Input Sample 2:

-1.2E+10

Output Example 2:

-12000000000
