    Comment/Request
    I wondering if the Modified Bessel function calculator is handling negative values for the order incorrectly. I am getting the same answer for v = 1, x = 2 as v = -1, x = 2. But I think these should not be the same.

    Saves time. No need to spend $$$ on expensive Calculus handbook, nor programming to execute the numeric calculations. Thanks!

    Purpose of use
    Evaluating Bessel functions of the first kind AND modified Bessel functions of the second kind. Certainly a quicker way than using a book of tables !
    Thank you !
