mindspore.ops.ApproximateEqual

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

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

outi={ if |xiyi|<tolerance,  True if |xiyi|tolerance,  False

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, lower priority data type will be converted to relatively highest priority data type. RuntimeError exception will be thrown when the data type conversion of Parameter is required.

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,) where means, any number of additional dimensions, its rank should 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.

Supported Platforms:

Ascend

Examples

>>> x = Tensor(np.array([1, 2, 3]), mindspore.float32)
>>> y = Tensor(np.array([2, 4, 6]), mindspore.float32)
>>> approximate_equal = ops.ApproximateEqual(2.)
>>> output = approximate_equal(x, y)
>>> print(output)
[ True  True  False]
