30 | .SH DESCRIPTION | |
31 | These functions calculate Bessel functions of the first | |
32 | and second kinds for real arguments and integer orders. | |
33 | .SH DIAGNOSTICS | |
34 | Negative arguments cause | |
35 | .I y0, y1, | |
36 | and | |
37 | .I yn | |
38 | to return a huge negative value | |
39 | and set | |
