Usage REAL X

COMPLEX C

C=FNBe(X)

Description

FNBe returns the values of the real and imaginary Kelvin functions of the first kind of the value x. The real part of the value returned is the value of ber(x) and the imaginary part is the value of bei(x). Although ber(x) and bei(x) are defined for all real values of x, large positive values of x may produce results greater than MAXREAL, the largest value representable.

Errors

FNBe causes an HTBasic error if it argument is not of type REAL. It also causes an error if the value of either component of the value returned would be larger than MAXREAL.
