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).
