tf.math.xlog1py(
    x, y, name=None
)

Given x and y, compute x * log1p(y). This function safely returns zero when x = 0, no matter what the value of y is.

Example:

tf.math.xlog1py(0., 1.)
<tf.Tensor: shape=(), dtype=float32, numpy=0.>
tf.math.xlog1py(1., 1.)
<tf.Tensor: shape=(), dtype=float32, numpy=0.6931472>
tf.math.xlog1py(2., 2.)
<tf.Tensor: shape=(), dtype=float32, numpy=2.1972246>
tf.math.xlog1py(0., -1.)
<tf.Tensor: shape=(), dtype=float32, numpy=0.>

Args
x	A tf.Tensor of type half, float32, float64, complex64, complex128
y	A tf.Tensor of type half, float32, float64, complex64, complex128
name	A name for the operation (optional).

Returns
x * log1p(y).
