Returns the Bessel function.

Syntax

expression.BesselJ (Arg1, Arg2)

expression A variable that represents a WorksheetFunction object.

Parameters

Name	Required/Optional	Data type	Description
Arg1	Required	Variant	The value at which to evaluate the function.
Arg2	Required	Variant	The order of the Bessel function. If n is not an integer, it is truncated.

Return value

Double

Remarks

If x is nonnumeric, BesselJ generates an error value.

If n is nonnumeric, BesselJ generates an error value.

If n < 0, BesselJ generates an error value.
