Usage                REAL X,Y
Y=FNS_k1(X)
 
Description                
FNS_k1 returns the value of the modified spherical Bessel function of the third kind and order one of x, k1(x). K1(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_k1 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.
