tf.sign
tf.sign
tf.sign
sign( x, name=None )
Defined in tensorflow/python/ops/math_ops.py
.
See the guide: Math > Basic Math Functions
Returns an element-wise indication of the sign of a number.
y = sign(x) = -1
if x < 0
; 0 if x == 0
or tf.is_nan(x)
; 1 if x > 0
.
Zero is returned for NaN inputs.
For complex numbers, y = sign(x) = x / |x|
if x != 0
, otherwise y = 0
.
Args:
-
x
: ATensor
orSparseTensor
. Must be one of the following types:half
,float32
,float64
,int32
,int64
,complex64
,complex128
. -
name
: A name for the operation (optional).
Returns:
A Tensor
or SparseTensor
, respectively. Has the same type as x
.
numpy compatibility
Equivalent to numpy.sign except for the behaviour for input values of NaN.
