BESSELJ

The BESSELJ function returns the integer Bessel function Jn(x).

BESSELJ(any-x-value, n-value)

any-x-value: A number value representing the x value at which you want to evaluate the function.

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.

Examples

=BESSELJ(25, 3) returns 0.108343081061509.

=BESSELJ(25, 3.9) also returns 0.108343081061509, because any decimal portion of n-value is ignored.

=BESSELJ(-25, 3) returns -0.108343081061509.
