Returns an element-wise indication of the sign of a number.
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.
tf.math.sign([0., 2., -3.]) <tf.Tensor: ... numpy=array([ 0., 1., -1.], dtype=float32)>
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, returns SparseTensor(x.indices, tf.math.sign(x.values, ...), x.dense_shape). If |
