Returns an element-wise indication of the sign of a number.
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)>
