COMPLEX C
C=FNS_h20(X)
 
Description                
FNS_h20 returns the value of the spherical Hankel function of the second kind and order zero of x, h0(2)(x). The real component returned contains j0(x) and the imaginary component returned contains -y0(x).
 
Errors                
FNS_h20 causes an HTBasic error if its argument is not of type REAL. It also causes an error if the value of x is near zero, since the imaginary component of h0(2)(0) is -.
