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 float32, float64 or float16.

• with_quant_attr (BOOLEAN) – Whether the operator has attributes used by quantization.

• name (str, optional) – Name for the operation (optional, default is None). For more information, please refer to Name.

Returns

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

Return type

out (Tensor)

Examples

import paddle

x = paddle.to_tensor([-0.4, -0.2, 0.1, 0.3])
out = paddle.expm1(x)
print(out)
# [-0.32967997, -0.18126924,  0.10517092,  0.34985882]
