Usage REAL X,Y
Y=FNK1(X)
Description
FNK1 returns the value of the modified cylindrical Bessel function of the second kind and order one of x, K1(x). K1(x) is defined for all positive values of x, but values of x near zero may cause the absolute value of the result to be larger than MAXREAL, the largest value representable.
Errors
FNK1 causes an HTBasic error if its argument is not of type REAL, if x is not positive, or if the result would be larger than MAXREAL.
