log10¶

paddle. log10 ( x, name=None ) [source]

Calculates the log to the base 10 of the given input tensor, element-wise.

\[\begin{split}Out = \\log_10_x\end{split}\]

Parameters

• x (Tensor) – Input tensor must be one of the following types: float32, float64.

• name (str|None) – The default value is None. Normally there is no need for user to set this property. For more information, please refer to Name

Returns

The log to the base 10 of the input Tensor computed element-wise.

Return type

Tensor

Examples

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) # [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) # [1.0]
