Returns True if two arrays are element-wise equal within a tolerance. The tolerance values are positive, typically very small numbers.The

relative difference (rtol * abs(b)) and the absolute difference atol are added together to compare against the absolute difference between a and b. If either array contains one or more NaNs, False is returned. Infs are treated as equal if they are in the same place and of the same sign in both arrays.

b NDArray

Input array to compare with a.

rtol double

The relative tolerance parameter(see Notes)

atol double

IsClose(NDArray, NDArray, double, double, bool)

Returns a boolean array where two arrays are element-wise equal within a tolerance. The tolerance values are positive, typically very small numbers.The
relative difference (rtol * abs(b)) and the absolute difference atol are added together to compare against the absolute difference between a and b. Warning: The default atol is not appropriate for comparing numbers that are much smaller than one(see Notes).

See also allclose

Notes: For finite values, isclose uses the following equation to test whether two floating point values are equivalent.

absolute(`a` - `b`) less than or equal to (`atol` + `rtol` * absolute(`b`))

Unlike the built-in math.isclose, the above equation is not symmetric in a and b -- it assumes b is the reference value -- so that isclose(a, b) might be different from isclose(b, a). Furthermore, the default value of atol is not zero, and is used to determine what small values should be considered close to zero.The default value is appropriate for expected values of order unity: if the expected values are significantly smaller than one, it can result in false positives. atol should be carefully selected for the use case at hand. A zero value for atol will result in False if either a or b is zero.

public override NDArray<bool> IsClose(NDArray a, NDArray b, double rtol = 1E-05, double atol = 1E-08, bool equal_nan = false)

Parameters

a NDArray

Input array to compare with b

b NDArray

Input array to compare with a.

rtol double

The relative tolerance parameter(see Notes)

atol double

The absolute tolerance parameter(see Notes)

equal_nan bool

Whether to compare NaN's as equal. If True, NaN's in a will be considered equal to NaN's in b in the output array.

Returns

NDArray<bool>

Returns a boolean array of where a and b are equal within the given tolerance.If both a and b are scalars, returns a single boolean value.

IsFinite(NDArray)

Test element-wise for finiteness (not infinity or not Not a Number).

public override NDArray<bool> IsFinite(NDArray a)

Parameters

a NDArray

Returns

NDArray<bool>

The result is returned as a boolean array.
