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`. NaNs are treated as equal if they are in the same place and if ``equal_nan=True``. Infs are treated as equal if they are in the same place and of the same sign in both arrays. Parameters ---------- a, b : Array | int | float | complex | bool Input objects to compare. At least one must be an array. rtol : array_like, optional The relative tolerance parameter (see Notes). atol : array_like, optional The absolute tolerance parameter (see Notes). equal_nan : bool, optional 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. xp : array_namespace, optional The standard-compatible namespace for `a` and `b`. Default: infer. Returns ------- Array A boolean array of shape broadcasted from `a` and `b`, containing ``True`` where `a` is close to `b`, and ``False`` otherwise. Warnings -------- The default `atol` is not appropriate for comparing numbers with magnitudes much smaller than one (see notes). See Also -------- math.isclose : Similar function in stdlib for Python scalars. Notes ----- For finite values, `isclose` uses the following equation to test whether two floating point values are equivalent:: absolute(a - b) <= (atol + rtol * absolute(b)) Unlike the built-in `math.isclose`, the above equation is not symmetric in `a` and `b`, so that ``isclose(a, b)`` might be different from ``isclose(b, a)`` in some rare cases. The default value of `atol` is not appropriate when the reference value `b` has magnitude smaller than one. For example, it is unlikely that ``a = 1e-9`` and ``b = 2e-9`` should be considered "close", yet ``isclose(1e-9, 2e-9)`` is ``True`` with default settings. Be sure to select `atol` for the use case at hand, especially for defining the threshold below which a non-zero value in `a` will be considered "close" to a very small or zero value in `b`. The comparison of `a` and `b` uses standard broadcasting, which means that `a` and `b` need not have the same shape in order for ``isclose(a, b)`` to evaluate to ``True``. `isclose` is not defined for non-numeric data types. ``bool`` is considered a numeric data-type for this purpose.

If `x` is inexact, NaN is replaced by zero or by the user defined value in the `fill_value` keyword, infinity is replaced by the largest finite floating point value representable by ``x.dtype``, and -infinity is replaced by the most negative finite floating point value representable by ``x.dtype``. For complex dtypes, the above is applied to each of the real and imaginary components of `x` separately. Parameters ---------- x : array | float | complex Input data. fill_value : int | float, optional Value to be used to fill NaN values. If no value is passed then NaN values will be replaced with 0.0. xp : array_namespace, optional The standard-compatible namespace for `x`. Default: infer. Returns ------- array `x`, with the non-finite values replaced. See Also -------- array_api.isnan : Shows which elements are Not a Number (NaN).

Each index in the input `x` is encoded as a vector of zeros of length `num_classes` with the element at the given index set to one. Parameters ---------- x : array An array with integral dtype whose values are between `0` and `num_classes - 1`. num_classes : int Number of classes in the one-hot dimension. dtype : DType, optional The dtype of the return value. Defaults to the default float dtype (usually float64). axis : int, optional Position in the expanded axes where the new axis is placed. Default: -1. xp : array_namespace, optional The standard-compatible namespace for `x`. Default: infer. Returns ------- array An array having the same shape as `x` except for a new axis at the position given by `axis` having size `num_classes`. If `axis` is unspecified, it defaults to -1, which appends a new axis. If ``x < 0`` or ``x >= num_classes``, then the result is undefined, may raise an exception, or may even cause a bad state. `x` is not checked.
