# numpy.nextafter

`numpy.``nextafter`(x1, x2, /, out=None, *, where=True, casting='same_kind', order='K', dtype=None, subok=True[, signature, extobj]) = <ufunc 'nextafter'>

  Return the next floating-point value after x1 towards x2, element-wise.

  Parameters: | x1 : array_like Values to find the next representable value of. x2 : array_like The direction where to look for the next representable value of x1. out : ndarray, None, or tuple of ndarray and None, optional A location into which the result is stored. If provided, it must have a shape that the inputs broadcast to. If not provided or None, a freshly-allocated array is returned. A tuple (possible only as a keyword argument) must have length equal to the number of outputs. where : array_like, optional Values of True indicate to calculate the ufunc at that position, values of False indicate to leave the value in the output alone. **kwargs For other keyword-only arguments, see the ufunc docs.
  Returns: | out : array_like The next representable values of x1 in the direction of x2.

  Examples

      >>> eps = np.finfo(np.float64).eps
      >>> np.nextafter(1, 2) == eps + 1
      True
      >>> np.nextafter([1, 2], [2, 1]) == [eps + 1, 2 - eps]
      array([ True,  True], dtype=bool)
