__bool__

array.__bool__() → bool

Converts a zero-dimensional array to a Python bool object.

Parameters:

self (array) – zero-dimensional array instance.

Returns:

out (bool) – a Python bool object representing the single element of the array.

Notes

Special cases

For real-valued floating-point operands,

  • If self is NaN, the result is True.

  • If self is either +infinity or -infinity, the result is True.

  • If self is either +0 or -0, the result is False.

For complex floating-point operands, special cases must be handled as if the operation is implemented as the logical OR of bool(real(self)) and bool(imag(self)).

Changed in version 2022.12: Added boolean and complex data type support.
