PASSAGE 2 (relevant lines)

Exception: exact conversions of an external base 10 value into internal base 2 (or hexadecimal) values, and vice versa, are not possible. For larger values, an approximation is necessary, because the effects of multiplying the also-converted exponent as a power of the base. For larger values, an approximation is necessary because the radix point cannot be less accurate than if the radix point were assumed to be on the left. ... Thus all significand values are approximations regardless of magnitude.
