Calculate the value of the Bessel function of the first kind of order n for the input argument x,
.
- Returns:
- Returns the value of the Bessel function of the first kind of order
n.
- jnf(
n, NaN) returns NaN. - jnf(
n, x) returns NaN for n < 0. - jnf(
n,
) returns +0.
- Note:
- For accuracy information for this function see the CUDA C Programming Guide, Appendix C, Table C-1.
