Angular units are always presented in decimal degrees. They can be specified to present data in ±180° format or 0-360° format. This choice in angular display convention can have important implications on the way that GR-Feature reports are displayed.
Several reporting fields for features will not convert. The delta, tolerance limits, and out-of-tolerance values are always reported with a sign in the range of -180º to 180º. This is because these value represent a relative difference value, not an absolute angle.
