FNBireturns the value of the Airy function of the second kind ofx. Note that sometimes Airy functions are written with an order, as in Bi3(x). In this notation, the functionFNBireturns the value of Bi0(x). Although Bi(x) is defined for all real values ofx, large positive values ofxmay produce results greater than MAXREAL, the largest value representable.
Errors
FNBicauses an HTBasic error if its argument is not of type REAL or if its result would be larger than MAXREAL.
