Table B.3 represents the operators and (built-in and factory) functions that apply to Python's numeric objects.

^[a] A result of "number" indicates any of the numeric types, perhaps the same as the operands.

^[b] ** has a unique relationship with unary operators; see Section 5.5.3 and Table 5.2.

^[c] Unary operator.
