BESSELY

BESSELY(x, n)

Returns the modified Bessel function represented by Y(x).

x	The value at which to evaluate the function.
n	The order of the function.

REMARKS

* This function is also known as the Weber or Neumann function.
* If any of the arguments are not numeric, then #VALUE! is returned.
* If "x" < 0, then #NUM! is returned.
* If "n" is not an integer, it is truncated.
* If "n" < 0, then #NUM! is returned.
