dpctl.tensor.sign¶
- dpctl.tensor.sign¶
sign(x, /, *, out=None, order=’K’)
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 (Union[usm_ndarray, None], optional) – Output array to populate. Array must have the correct shape and the expected data type.
order ("C","F","A","K", optional) – Memory layout of the new output array, if parameter out is
None. Default: “K”.
- Returns:
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.
