The accuracy can be improved by rounding instead of truncating when converting from real to fixed-point, or by allowing more bits for the fractional part.
精度可以提高通过舍入而不是删除从真正的定点时,或允许更多的位小数部分。

Some fixedpoint theory of fractional linear transformation is discussed and it is shown that one kind of transformation from unit circular to unit circular has only some real fixed points.
