j0(), j0f(),
j1() and j1f() compute the
Bessel function of the first kind of the order 0 and the
order 1, respectively, for the real value
x; the functions jn() and
jnf() compute the Bessel function of the
first kind of the integer order n for the real value
x.
The functions y0(),
y0f(), y1() and
y1f() compute the linearly independent
Bessel function of the second kind of the order 0 and the
order 1, respectively, for the positive
integer value x (expressed as a
double); the functions yn() and
ynf() compute the Bessel function of
the second kind for the integer order n for the
positive integer value x (expressed
as a double).
EDOM and a reserve operand fault is generated.
