expm1¶

paddle. expm1 ( x, name=None ) [source]

Expm1 Operator. Computes expm1 of x element-wise with a natural number \(e\) as the base.

\[out = e^x - 1\]

Parameters

x (Tensor) – Input of Expm1 operator, an N-D Tensor, with data type int32, int64, float16, float32, float64, complex64 or complex128.
name (str, optional) – Name for the operation (optional, default is None). For more information, please refer to Name.

Returns

Tensor. Output of Expm1 operator, a Tensor with shape same as input.

Examples

           >>> import paddle

>>> x = paddle.to_tensor([-0.4, -0.2, 0.1, 0.3])
>>> out = paddle.expm1(x)
>>> print(out)
Tensor(shape=[4], dtype=float32, place=Place(cpu), stop_gradient=True,
[-0.32967997, -0.18126924,  0.10517092,  0.34985882])
