Overview

Consider the following task:

Given a positive integer n > 0, output its integer square root. The integer square root of a number n is the largest value of x where x² ≤ n, usually expressed with the formula floor(sqrt(n)).

Examples: 25 -> 5, 24 -> 4, 40 -> 6, 1 -> 1.

This task is easy enough on its own. However, in this challenge, your task is to solve this in as many languages as possible using a set of only 25 characters.

Example

First, you need to pick a set (no duplicates) of 25 bytes. It may look something like this (note the leading space):

 ()*-.05:=>Mabdhilmnqrst|

Your challenge is then to, using only characters in this set, construct a solution to the problem in as many text based (sorry, Piet) languages as possible. You can use characters as many times as necessary, but you must not use characters outside the set.

The solutions can be either full programs or functions, but not snippets. For example, using this set of characters, I could do:

M -> (int) Math.sqrt(M)    // Java (lambda expression)
M => Math.sqrt(M)|0        // Javascript (unnamed function)
lambda M: int(M**.5)       // Python (lambda function)

As I've used 3 languages, this would give me a score of 3.

Please also include the set of bytes you are using in your answer.

Rules

This is a rosetta-stone challenge - your score is the number of languages your submission includes. The highest score wins. Standard loopholes apply.
For this challenge, a 'language' counts as a distinctly different programming language - multiple versions of the same language (Python 2, Python 3, etc) are banned.
Programs only need to work for inputs within the language's standard integer range.
Programs with the exact same source code (polyglots) are not allowed.
To be more specific, it is a set of bytes, not characters - so you can use the 05AB1E £ and the Jelly ɱ as the same character (because they have the same codepoint).

Please don't feel as though you have to beat all other solutions - if you have an interesting answer, post it!

2Can our solution be in Piet if we have the code be the raw ppm? (e.g. P3 10 10 255...) – Post Rock Garf Hunter – 2017-01-10T02:58:21.160

We need another pixel based language so we can have polyglots with poor old piet – MildlyMilquetoast – 2017-01-10T03:37:13.417

2Can we count a polyglot of A and B as language A if we provide another solution that only works in B? – Post Rock Garf Hunter – 2017-01-10T05:25:05.317

Could you clarify "distinctly different"? For example, is Numberwang--using digits instead of []<>.,+--- distinctly different from Brainfuck? What about SNUSP, a 2D Brainfuck derivative? For both of them, the resulting code would not work in Brainfuck.

@WheatWizard you can't have two programs that are exactly the same, but if you modify one to be different then it's allowed. And yes, if you really must, you can use the raw ppm as "text" for Piet :P – FlipTack – 2017-01-10T07:25:33.843

@JungHwanMin the second is definitely distinctly different as it's 2D. I'd also say numberwang is sufficiently different as it has a different character set. – FlipTack – 2017-01-10T07:27:19.030

@JungHwan generally, a different language is a different creator, different syntax , etc. However with esoteric languages the line gets blurry. Trivial, "1 new command" modifications of brainfuck aren't really different to bf, but larger derivatives like the 2D one you linked encourages different ways of programming and so counts as a different language. – FlipTack – 2017-01-10T08:01:37.603

C, 23 Bytes f(x){return pow(x,.5);} and 20 characters used f(x){retun powx,.5;} – Wade Tyler – 2017-01-11T05:20:14.383

@WadeTyler Not sure why you've commented that, but you should know that you've counted x twice in your character set. Also, if you name the function something like p that's already in the set then you don't have to count f. – FlipTack – 2017-01-15T14:03:26.410

@FlipTack I wanted to make it as a post, for others who didn't use C in theirs because of reasons, and talked with someone that it would be a better idea to leave is a comment on your post so others can see it. – Wade Tyler – 2017-01-15T14:14:00.160

Try adding flr.(tt ^.5) for Wonder (no added chars). – Mama Fun Roll – 2017-01-10T02:24:16.433

If you would like to add {}[] you can add Brain-Flak. Here's the program

– Post Rock Garf Hunter – 2017-01-10T02:45:37.590

If you added ~, you could do sqrt~~ in Stacked; it takes input from the TOS and leaves output on the stack.

julia also has isqrt – rahnema1 – 2017-01-10T04:14:14.930

isqrt in Julia wouldn't count because polyglots are not allowed. – JungHwan Min – 2017-01-10T05:41:07.900

The Pyth one would be shorter and more readable if you used ttt5 instead of +>5 0>5 0. – PurkkaKoodari – 2017-01-10T12:40:01.187

C, 23 Bytes f(x){return pow(x,.5);} and 20 characters used f(x){retun powx,.5;} You can replace the curly brackets with round brackets. – Wade Tyler – 2017-01-11T05:21:40.083

Per meta consensus, this code should be okay, even though no interpreters are currently available.

Using ()*/12 dlinpqrstu and newline (18 characters) so far.

Common Lisp

isqrt

A built-in function.

QBasic

input q
print int(sqr(q))

Python 3

print(int(int(input())**(1/2)))

Python 3 used for floating-point division without decimal points.

Pip

q**/2//1

Unnecessarily golfy to show off the unary inversion operator /. Takes input from stdin. Try it online!

tinylisp

(d sqrt (q((n nsqr input) (i (l input nsqr) (s n 1) (sqrt (s n (s 1 2)) (s 2 (s (s (s 1 n) n) nsqr)) input)))))
(q((input)(sqrt 1 1 input)))

sqrt is a helper function whose arguments are: the current guess n, n squared, and the input number. If input is less than nsqr, we've gone too far, so return n minus 1; otherwise, recurse, adding 1 to n and adding n + n + 1 to nsqr. (The math is a bit complicated because tinylisp only has subtraction built in.) The second line defines our actual function, which takes a single input and returns the result of sqrt with n starting at 1.
