Test element-wise for positive or negative infinity.

For full documentation refer to numpy.isinf.

Limitations

Input array is supported as dpnp.ndarray. Otherwise the function will be executed sequentially on CPU. Input array data types are limited by supported DPNP Data types. Parameter out is supported only with default value None. Parameter where is supported only with default value True.
