Claim 45:
46. A computer-readable storage medium storing instructions that, when executed, cause one or more processors of a point cloud decoder to:
obtain a value of a secondary residual for geometry coding a current predictive tree node of the point cloud; and
decode the value of the secondary residual, wherein, the instructions that cause the or more processors to decode the value comprise instructions that cause the one or more processors to:
decode, using a first set of context-adaptive binary arithmetic coding (CABAC) contexts, prefix bins of a syntax element, the syntax element having a value that specifies an absolute value of the value of the secondary residual; and
decode, using a second set of CABAC contexts that is different than the first set of contexts, suffix bins of the syntax element.
