 * SpecialFunctions.jl doesn't always preserve the correct input type so some of the calculations may be done in Float64. This might skew the benchmarks for `Bessels.jl`.

+# Current Development Plans
+
+- More robust implementations of `besselj(nu, x)` and `bessely(nu, x)`
+- Support non-integer orders
+- Support complex arguments
