BESSELY

The BESSELY function returns the integer Bessel function Y_n(x).

BESSELY(pos-x-value, n-value)

pos-x-value: A number value representing the x value at which you want to evaluate the function. pos-x-value must be greater than 0.

n-value: A number value representing the order of the function. n-value must be greater than or equal to 0. Any decimal portion is ignored.

Notes

This form of the Bessel function is also known as the Neumann function.

Examples

=BESSELY(25, 3) returns 0.117924850396893.

=BESSELY(25, 3.9) also returns 0.117924850396893, because any decimal portion of n-value is ignored.

=BESSELY(-25, 3) returns an error, because negative or zero values are not permitted.
