| 131If these functions are successful, 132the computed value is returned. | 131These routines return values of their respective Bessel functions. 132For large positive inputs, they may underflow and return \*(Pm0. 133.Pp 134The following applies to 135.Fn y0 , 136.Fn y0f , 137.Fn y1 , 138.Fn y1f , 139.Fn yn , 140and 141.Fn ynf . 142If 143.Fa x 144is negative, these routines will generate an invalid exception and 145return \*(Na. 146If 147.Fa x 148is 0 or a sufficiently small positive number, these routines 149will generate an overflow exception and return -\*(If. |
