jax.numpy.isposinf

jax.numpy.isposinf(x, out=None)

Test element-wise for positive infinity, return result as bool array.

LAX-backend implementation of isposinf().

Original docstring below.

Parameters

x (array_like) – The input array.

Returns

out – A boolean array with the same dimensions as the input. If second argument is not supplied then a boolean array is returned with values True where the corresponding element of the input is positive infinity and values False where the element of the input is not positive infinity.

If a second argument is supplied the result is stored there. If the type of that array is a numeric type the result is represented as zeros and ones, if the type is boolean then as False and True. The return value out is then a reference to that array.

Return type
