Octal Fractions

Input

The input to your program will consist of octal numbers, one per line, to be converted. Each input number has the form $0. d_{1} d_{2} d_{3} \dots d_{k}$ 0.d_1d_2d_3 \ldots d_k, where the $d_{i}$ d_i are octal digits (0..7). There is no limit on $k$ .

Output

Your output will consist of a sequence of lines of the form $0. d_{1} d_{2} d_{3} \dots d_{k} [8] = 0. D_{1} D_{2} D_{3} \dots D_{m} [10]$ 0.d_1d_2d_3 \ldots d_k~[8] = 0.D_1D_2D_3 \ldots D_m~[10]

where the left side is the input (in octal), and the right hand side the decimal (base $10$ ) equivalent. There must be no trailing zeros, i.e. $D_{m}$ D_m is not equal to $0$ .
