Summary

This function calculates the modified Bessel function of the second kind evaluated for purely imaginary arguments.

Syntax

BESSELK(value,order)

Arguments

This function has these arguments:

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

Remarks

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)

BESSELK(1.85,2) gives the result 0.32165379
