<br />

    tf.raw_ops.Sign(
        x, name=None
    )

`y = sign(x) = -1` if `x < 0`; 0 if `x == 0`; 1 if `x > 0`.

For complex numbers, `y = sign(x) = x / |x|` if `x != 0`, otherwise `y = 0`.

#### Example usage:

    tf.math.sign([0., 2., -3.])
    <tf.Tensor: shape=(3,), dtype=float32, numpy=array([ 0.,  1., -1.], dtype=float32)>
