This caused the SQLite text-to-float converter routine to give incorrect results for values between '1.8446744073709550592eNNN' and '1.8446744073709551609eNNN' for any exponent NNN. This problem was introduced by check-in [761d8fd18b0ee868] and first appeared in version 3.47.0 and was reported by forum post 569a7209179a7f5e. Fixed by this check-in.

| 14:31 | [cedda44359] part of check-in [4a790d3b28] Change the rounding behavior of float point to decimal conversions such that if the next digit is 4 but the value is within one epsilon of the next digit being 5 and if the epsilon is small compared the number of digits to be rendered, then go ahead and round up anyhow, even though the correct behavior would be to round down.
