dpnp.tensor.sign

dpnp.tensor.sign

Computes an indication of the sign of each element x_i of input array x using the signum function.

The signum function returns -1 if x_i is less than 0, 0 if x_i is equal to 0, and 1 if x_i is greater than 0.

Parameters:
  • x (usm_ndarray) -- Input array, expected to have a numeric data type.

  • out ({None, usm_ndarray}, optional) --

    Output array to populate. Array must have the correct shape and the expected data type.

    Default: None.

  • order ({"C", "F", "A", "K"}, optional) --

    Memory layout of the new output array, if parameter out is None.

    Default: "K".

Returns:

out -- An array containing the element-wise result of the signum function. The data type of the returned array is determined by the Type Promotion Rules.

Return type:

usm_ndarray
