tf.raw_ops.Sign

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

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.
