tf.math.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.
| 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.If x is a SparseTensor, returnsSparseTensor(x.indices, tf.math.sign(x.values, ...), x.dense_shape) |
