| 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 | |
| 40 | .I errno | |
| 41 | to EDOM. |
