 // character.
 //
 // The produced digits might be too short in which case the caller has to fill
 // the gaps with '0's.
 // Example: FastFixedDtoa(0.001, 5, ...) is allowed to return buffer = "1", and
 // decimal_point = -2.
 // Halfway cases are rounded towards +/-Infinity (away from 0). The call
 // FastFixedDtoa(0.15, 2, ...) thus returns buffer = "2", decimal_point = 0.
 // The returned buffer may contain digits that would be truncated from the
 // shortest representation of the input.
 //
 // This method only works for some parameters. If it can't handle the input it
 // returns false. The output is null-terminated when the function succeeds.
