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
