log10

paddle. log10 ( x, name=None ) [源代码]

Log10激活函数(计算底为10的对数)

\[\begin{split}\\Out=log_{10} x\\\end{split}\]
参数:
  • x (Tensor) – 该OP的输入为Tensor。数据类型为float32,float64。

  • name (str,可选) – 该参数供开发人员打印调试信息时使用,具体用法请参见 Name ,默认值为None。

返回:Log10算子底为10对数输出

返回类型: Tensor - 该OP的输出为Tensor,数据类型为输入一致。

代码示例

import paddle

# example 1: x is a float
x_i = paddle.to_tensor([[1.0], [10.0]])
res = paddle.log10(x_i) # [[0.], [1.0]]

# example 2: x is float32
x_i = paddle.full(shape=[1], fill_value=10, dtype='float32')
paddle.to_tensor(x_i)
res = paddle.log10(x_i)
print(res.numpy()) # [1.0]

# example 3: x is float64
x_i = paddle.full(shape=[1], fill_value=10, dtype='float64')
paddle.to_tensor(x_i)
res = paddle.log10(x_i)
print(res.numpy()) # [1.0]
