Description

x 
Required 
The value at which to evaluate the function. 
n 
Required 
The order of the Bessel function. If n is not an integer, it is truncated. 
• If x is nonnumeric, BESSELY returns the #VALUE! error value. 
• If n is nonnumeric, BESSELY returns the #VALUE! error value. 
• If n < 0, BESSELY returns the #NUM! error value. 
The BESSELY function returns the Bessel function, which is also called the Weber function or the Neumann function.
