Test whether all data are element-wise equal to other, broadcastable data.

Two real numbers x and y are considered equal if |x-y|<=atol+rtol|y|, where atol (the tolerance on absolute differences) and rtol (the tolerance on relative differences) are positive, typically very small numbers. See the atol and rtol parameters.

Parameters:

y:

The object to be compared with the data array. y must be broadcastable to the data array and if y has units then they must be compatible. May be any object that can be converted to a Data object (which includes numpy array and Data objects).

atol: float, optional

The tolerance on absolute differences between real numbers. The default value is set by the atol function.

rtol: float, optional

The tolerance on relative differences between real numbers. The default value is set by the rtol function.

Returns:

bool

Returns True if the data are equal within the given tolerance; False otherwise.
