DESCRIPTION

40       These  functions  calculate  Bessel  functions  of the first and second
41       kinds for real arguments and integer orders.
42

DIAGNOSTICS

44       Negative arguments cause besy0, besy1, and besyn to return a huge nega‐
45       tive value. The system error code will be set to EDOM (33).
