Usage REAL X,Y

Y=FNS_k0(X)

Description

FNS_k0 returns the value of the modified spherical Bessel function of the third kind and order zero of x, k0(x). K0(x) is defined for all values of x except zero, but large negative values of x or values of x near zero may cause the result to be larger in magnitude than MAXREAL, the largest value representable.

Errors

FNS_k0 causes an HTBasic error if its argument is not of type REAL, if x is zero, or if the result would be larger than MAXREAL.
