Personally, I found the [FORD suite](https://github.com/Fortran-FOSS-Programmers/ford) a lot better for Fortran documentation. It has structured documentation and one could (easily?) parse it.

I found some other projects which have alrady implemented various snippets. Maybe we should just copy-paste them... - [atom - language-fortran](https://atom.io/packages/language-fortran): snippet file [here](https://github.com/dparkins/language-fortran/blob/master/snippets/language-fortran.cson) - [vscode - fortran](https://marketplace.visualstudio.com/items?itemName=Gimly81.fortran): snippet file...

It works under `ifort` without any additional options. In `gfortran` one needs to enable "DEC compatibility mode". From the [documentation](https://gcc.gnu.org/onlinedocs/gfortran/Fortran-Dialect-Options.html): `-fdec-structure` _Enable DEC STRUCTURE and RECORD as well as UNION,...

In `Base/mpfr.jl` there is a [`factorial(x::BigFloat)`](https://github.com/JuliaLang/julia/blob/26a721b28ad56c006957ee1f2de083befcfe7904/base/mpfr.jl#L640) implementation which actually just checks that x is integer. This is where the error comes from: `SpecialFunctions.factorial` calls the `Base.factorial` for `BigFloat` arguments ([link](https://github.com/JuliaMath/SpecialFunctions.jl/blob/281292fffb97d922b2597ae570d36b061792cac9/src/gamma.jl#L891)...

Created a discussion at [discourse.julialang.org](https://discourse.julialang.org/t/base-factorial-extending-and-overwriting-functions-in-specialfunctions/53486).

Depending on pr #297 `factorial` might be removed from SpecialFunctions.jl

> The problem that i found is that is not consistent how bessely works. There is only a `BigFloat` implementation of `bessely(nu, x)` for integer values of `nu`. This explains...

The make.jl documentation script throws tons of errors. Some are regarding the newly implemented function `binomial`. Excerpts from the warnings: ``` $ cd docs && julia make.jl ... Warning: no...

A Todo list (taken from the issue #282) - [x] implement the function - [ ] write documentation - [x] wikipedia - [ ] dlmf - [x] write tests I...

I'd like to work on this. I have the following things in mind - implement the function - exactly the one-liner that @stevengj wrote before - write documentation (link to...
