It'd make a *lot* more sense there, instead of having it in a separate library. It's well-known that there's a lot of remaining std.math functions which need proper single/double precision implementations, and ldexp is one of them.

Yes, Mir is Boost licensed, but I don't work on Phobos anymore. Mir libraries are going to be independent of Phobos.

Using libm's ldexp() is also likely going to be 2-5x slower than using the implementation you've written for mir.ldexp(). For one, your version will be inlined! -- Iain

Here is a small benchmark that compares Mir, C and Phobos implementations: https://github.com/libmir/mir-core/blob/master/bench_ldexp_frexp.d Mir ldexp is 2.5 (5.5 - dmd) times faster for double and float. You could double the speed of ldexp if you actually used the checkedint compiler intrinsics rather than implementing it yourself. Using libm's ldexp() is also likely going to be 2-5x slower than using the implementation you've written for mir.ldexp(). For one, your version will be inlined! Mir has support for LLVM checkedint intrinsics. GDC checkedint intrinsics are not yet integrated in Mir. https://github.com/libmir/mir-core/blob/master/source/mir/checkedint.d

I'm using DCD through my beloved Emacs. Is there a more

I looked into lsp-mode a bit more, and actually, after installing
it, its dependencies and d-mode, a few lines of configuration in
Emacs' init file are enough apparently:
(require 'lsp)
(add-hook 'd-mode-hook #'lsp)
(lsp-register-client
(make-lsp-client
:new-connection (lsp-stdio-connection
'("~/.dub/packages/.bin/dls-latest/dls"))
:major-modes '(d-mode)
:server-id 'dls))
After adding this, and installing DLS (`dub fetch dls; dub run
dls:bootstrap`), it should be working.

I'm glad you sorted it out, David. If you need further help just
file an issue.
