This should be enough for all cases, because: A double has 53 bits of mantissa (including the implicit 1 bit), which is 53*ln(2)/ln(10) = 15.95 decimal digits. However the leading decimal digit may encode less than the usual 3.32 bits, which will push this over the edge to requiring 17 decimal digits.
