46 These functions return the first derivative with respect to /x/ of the corresponding Bessel function.
48 The return type of these functions is computed using the __arg_promotion_rules
49 when T1 and T2 are different types. The functions are also optimised for the
50 relatively common case that T1 is an integer.
54 The functions return the result of __domain_error whenever the result is
59 There are two sets of test values: spot values calculated using
60 [@http://www.wolframalpha.com/ wolframalpha.com],
61 and a much larger set of tests computed using
62 a relation to the underlying Bessel functions that the implementation
67 The accuracy of these functions is broadly similar to the underlying Bessel functions.
