| Argument | Description |
|---|---|
| value | Value at which to evaluate the function |
| order | Number representing the order of the function; if it is not an integer, it is truncated |

This function is also called the Neumann function. If value or order is nonnumeric then a #Value! error is returned. If order is less than 0 then the #NUM! error is returned.
Data Types
Accepts numeric data for both arguments. Returns numeric data.
Examples
BESSELK(A4,D5)
BESSELK(R4C1,R5C4)
