BESSELI(x, n)

Returns the Bessel function evaluated for purely imaginary arguments.

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

REMARKS

* If any of the arguments are not numeric, then #VALUE! is returned.
* If "n" is not an integer, it is truncated.
* If "n" < 0, then #NUM! is returned.
