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.])

Args
x	A Tensor. Must be one of the following types: bfloat16, half, float32, float64, int32, int64, complex64, complex128.
name	A name for the operation (optional).

Returns
A Tensor. Has the same type as x.
