| 47 | .SH DESCRIPTION | |
| 48 | These functions calculate Bessel functions of the first and second kinds | |
| 49 | for real arguments and integer orders. | |
| 50 | .SH DIAGNOSTICS | |
| 51 | Negative arguments cause \fIbesy0, besy1,\fR and \fIbesyn\fR to return a huge | |
| 52 | negative value. The system error code will be set to EDOM (33). | |
