dpnp.isfinite

dpnp.isfinite(x, /, out=None, *, where=True, order='K', dtype=None, subok=True, **kwargs)[source]

Test element-wise for finiteness (not infinity or not Not a Number).

For full documentation refer to numpy.isfinite.

Limitations

Parameters x is only supported as either dpnp.ndarray or dpctl.tensor.usm_ndarray. Parameters where, dtype and subok are supported with their default values. Otherwise the function will be executed sequentially on CPU. Input array data types are limited by supported DPNP Data types.

dpnp.isinf: Test element-wise for positive or negative infinity.
dpnp.isneginf: Test element-wise for negative infinity, return result as bool array.
dpnp.isposinf: Test element-wise for positive infinity, return result as bool array.
dpnp.isnan: Test element-wise for NaN and return result as a boolean array.

Notes

Not a Number, positive infinity and negative infinity are considered to be non-finite.

Examples

>>> import dpnp as np
>>> x = np.array([-np.inf, 0., np.inf])
>>> np.isfinite(x)
array([False,  True, False])
