1. A decoding method comprising:
determining a numerical range based on whether intra prediction or inter prediction is to be used to decode encoded first information of a current three-dimensional point; and
switching a context between a first context and a second context to entropy-decode the encoded first information, based on whether an absolute value of decoded second information of the current three-dimensional point is included in the numerical range determined.
