__pow__

array.__pow__(other: int | float | complex | array, /) → array

Calculates an implementation-dependent approximation of exponentiation by raising each element (the base) of an array instance to the power of other_i (the exponent), where other_i is the corresponding element of the array other.

Parameters:

  • self (array) – array instance whose elements correspond to the exponentiation base. Should have a numeric data type.

  • other (Union[int, float, complex, array]) – other array whose elements correspond to the exponentiation exponent. Must be compatible with self (see Broadcasting). Should have a numeric data type.

Returns:

out (array) – an array containing the element-wise results. The returned array must have a data type determined by Type Promotion Rules.

Notes

  • Element-wise results, including special cases, must equal the results returned by the equivalent element-wise function pow().

  • If both self and other have integer data types, the result of __pow__ when other_i is negative (i.e., less than zero) is unspecified and thus implementation-dependent.

  • If self has an integer data type and other has a floating-point data type, behavior is implementation-dependent, as type promotion between data type “kinds” (e.g., integer versus floating-point) is unspecified.

Changed in version 2022.12: Added complex data type support.
