When the computed significand lands exactly on 10 ^ (precision - 1), the
value sits right on a power-of-10 boundary where two representations are
possible. For example, consider 1e-21. The nearest double value to 1e-21
is actually slightly less than 1e-21. So with `toPrecision(16)`, we must
choose between:
exponent=-21 significand=1000000000000000 -> 1.000000000000000e-21
exponent=-22 significand=9999999999999999 -> 9.999999999999999e-22
The spec dictates that we must pick the value that is closer to the true
value. In this case, the second value is actually closer.
