Angle Rounding
Contents
It is possible to display zodiac angles in either of two ways. In the "Preferences" dialog, "Misc" tab if the angle rounding option is off, then when angles are displayed they will simply be truncated from their full precision. If the angle rounding option is on, then the displayed angle will be rounded to the nearest displayed unit (i.e. to the nearest minute if the angle is displayed in degrees and minutes, or to the nearest second if the angle is displayed in degrees minutes and seconds). The only exception to this rounding rule occurs for zodiacal longitudes just prior to a sign boundary. In this particular case no rounding is applied, to ensure that the displayed angle does not appear to be in the following sign before the ingress actually occurs.
Some examples follow.

Any charts or reports that are generated display any angles according to the current setting of this option. Note that this option does not affect the way in which angles are calculated or stored internally (they are always stored to a high precision, regardless of this option) - it only affects the manner in which angles are displayed.
