log10¶

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

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

\[Out = \log_10_x\]

Parameters

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

• name (str, optional) – Name for the operation (optional, default is None). 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]
