bessel_y0(x) computes the Bessel function of the second kind of order 0 of
Fortran 2008 and later
result = bessel_y0(x)
x- The type shall be
real, and it shall be scalar.
The return value is a scalar of type
real. It has the same kind as
program test_besy0 real(8) :: x = 0.0_8 x = bessel_y0(x) end program test_besy0
