mindspore.ops.ApproximateEqual

class mindspore.ops.ApproximateEqual(tolerance=1e-05)

Returns True if abs(x-y) is smaller than tolerance element-wise, otherwise False.

$$\begin{array}{r}ou{t}_i=\{\begin{array}{ll}& \text{ if }|x_i-y_i|<\text{tolerance},True\\ & \text{ if }|x_i-y_i|\ge \text{tolerance},False\end{array}\end{array}$$

where tolerance indicates Acceptable maximum tolerance.

Inputs of x and y comply with the implicit type conversion rules to make the data types consistent. If they have different data types, the lower precision data type will be converted to the relatively highest precision data type.

Parameters

tolerance (float) – The maximum deviation that two elements can be considered equal. Default: 1e-05 .

Inputs:

• x (Tensor) - A tensor. Must be one of the following types: float32, float16. $(N,\ast )$ where $\ast$ means, any number of additional dimensions, its rank should be less than 8.

• y (Tensor) - A tensor of the same type and shape as x.

Outputs:

Tensor, the shape is the same as the shape of x, and the data type is bool.

Raises

• TypeError – If tolerance is not a float.

• TypeError – If the data type of x, y conversion of Parameter is given but data type conversion of Parameter is not supported.

Supported Platforms:

Ascend GPU CPU

Examples

>>> import mindspore
>>> import numpy as np
>>> from mindspore import Tensor, ops
>>> x = Tensor(np.array([1, 2, 3]), mindspore.float32)
>>> y = Tensor(np.array([2, 3, 6]), mindspore.float32)
>>> approximate_equal = ops.ApproximateEqual(2.)
>>> output = approximate_equal(x, y)
>>> print(output)
[ True  True  False]
