The bucketizer.mean.circular function returns the the circular mean of all the values found in the bucket.
The associated location is the centroid of all the encountered locations. The associated elevation is the mean of the encountered elevations.

The bucketizer.mean.circular function can only be applied to values of type LONG or DOUBLE, when applied to STRING or BOOLEAN it does not return any value.

If any tick is undefined, no value will be returned. Use bucketizer.mean.circular.exclude-nulls if your GTS contain nulls.

The bucketizer.mean.circular function expects a positive, finite, numeric period on top of the stack, this period will be used to determine the span of circular values, use for example 360.0 if you wish to compute the circular mean of degree angles.

bucketizer.mean.circular is available since version 1.0.11.
