Produce a text file that prints "Hello World!" in as many programming languages as possible when compiled/interpreted, while also being as short as possible.
The score for your submission is calculated as C / 2 ^ ((L - 1) / 4), where "C" is the length of the text file in characters and "L" is the number of languages that the program is valid in. Lowest score wins, of course.

Works in Perl 6 too – Hotkeys – 2016-02-03T21:37:38.387
1It also works in R and Julia (and surely in many other languages). – Sven Hohenstein – 2013-02-19T07:20:20.200
works in PHP too – jdstankosky – 2013-03-08T14:39:32.963
This print() syntax is also valid in Transact-SQL. http://pastebin.com/is2mqRJC

@jdstankosky, that exact code not works in PHP. http://pastebin.com/9x6HactK
– manatwork – 2013-03-09T16:17:06.1631
Kind of forcing the limits, but we can say it works in JavaScript too, as some command line interpreters provide print() function for outputting. http://pastebin.com/6fXtgFER
@manatwork Well, <?php print("Hello World!") ?> since you want to get specific, but I'm not counting the <?php ?> tags. – jdstankosky – 2013-03-11T20:32:12.463
Works in TI-Basic too. – Timtech – 2013-12-31T00:38:30.823

Assuming it is valid in the 8 languages listed, the score is at most(as in numerically) 21/2^((8-1)/4)=6.2433373537642856 – Naruyoko – 2019-08-30T16:45:57.153

It won't work in Hello due to extra characters. – user75200 – 2017-10-26T07:03:48.243
I'm pretty sure a lot of these (HQ9, Hello, and variants) don't count because they're not "real" programming languages. – KSmarts – 2017-11-02T14:47:10.177
Yes they're. They're real languages. But they may or mayn't work. And Hello++ discards non-h characters. Hello++++ discards all not part of "Hello world!" – user75200 – 2017-11-04T18:36:30.863
And there's no HQ9. – user75200 – 2017-11-12T10:47:33.710

NOTE: There is no TIO for Madbrain, so you'll have to trust me on this one. I did, however, write an (admittedly not really well-written (but hey, at least it works!)) interpreter for Madbrain, which is on the esolangs wiki.

I admit, Madbrain reaches the BF code, but it doesn't do anything, so I didn't include it here.
Brainfuck (and a lot of BF derivatives) sees:
++++++[-]+[-->-[>>+>-----<<]<--<---]>-.>>>+.>>..+++.>>.>.<<<.+++.------.<<-.>>>>+.
BF ignores everything that isn't ><+-.,[], so it ignores most of the Madbrain code. However, there are some +s in the Madbrain code (that's what the ++++++ is), so you need to add [-] after that which sets the current cell to 0.
The code after ++++++[-] is the code for printing Hello World!.

Feel free to write in any language you desire, it matters not when it was made. – user75200 – 2017-10-29T17:54:24.677

This question is similar to this other one, but in this case, you can share "Hello World" among some languages if you wish.
