They could separated by commas. The AUNITS system variable could set angle displaying formats. The POLARMODE system variable must be set to be 5, or the POLARADDANG does not have effect. When using fractions of an angle, set the AUPREC system variable (angular precision) to a higher value. Otherwise, the POLARADDANG value will be rounded off. . --- ## Other versions with matching text [GstarCAD 2016](../../../2016/System%20Variables/P/POLARADDANG%20System%20Variable.md) · [GstarCAD 2017](Help%20System/GSTARCAD/2017/System%20Variables/P/POLARADDANG%20System%20Variable.md) · [GstarCAD 2018](Help%20System/GSTARCAD/2018/System%20Variables/P/POLARADDANG%20System%20Variable.md) · [GstarCAD 2019](Help%20System/GSTARCAD/2019/System%20Variables/P/POLARADDANG%20System%20Variable.md) · [GstarCAD 2020](Help%20System/GSTARCAD/2020/System%20Variables/P/POLARADDANG%20System%20Variable.md)
