     * Excel Function:
     *        OCT2BIN(x[,places])
     *
     * @param array|string $value The octal number you want to convert. Number may not
     *                          contain more than 10 characters. The most significant
     *                          bit of number is the sign bit. The remaining 29 bits
     *                          are magnitude bits. Negative numbers are represented
     *                          using two's-complement notation.
     *                      If number is negative, OCT2BIN ignores places and returns
     *                          a 10-character binary number.
     *                      If number is negative, it cannot be less than 7777777000,

     *                      If number is not a valid octal number, OCT2BIN returns
     *                          the #NUM! error value.
     *                      If OCT2BIN requires more than places characters, it
     *                          returns the #NUM! error value.

     *                          OCT2BIN uses the minimum number of characters necessary.
     *                          Places is useful for padding the return value with
     *                          leading 0s (zeros).
     *                      If places is not an integer, it is truncated.
