What is MathAddons?

MathAddons is a simple yet useful module with math functions such as average, scientific notation, fraction conversion, and more!

Using any of the functions is as simple as:

-- Within a LocalScript or ServerScript and assuming MathAddons is placed in ReplicatedStorage

local Math = require(game.ReplicatedStorage.MathAddons)
local numbers = {1,2,3,4,5,6}
local average = Math.avg(numbers)
print(average) -- 3.5

FAQ

? What does MathAddons bring that the regular math functions don’t?

! This module contains 27 unique functions with different levels of complexity, from coinflips to integration.

? Is there a performance gap?

! I have yet to do the actual benchmarking, however, I will say some functions such as integration do rely on loops, other than the functions rely on a great amount of looping, they won’t have a noticeable performance impact.

? How frequently does this module get updated?

! There isn’t any schedule, it’s just when I learn/come up with a new math concept to add.

? Some of these functions are easy to make, why should I use them through a module?

! And to that I say you are perfectly justified thinking that way! I am making this module as a student as opposed to an expert. I try to remove simplistic functions or make them more useful and complex (They usually end up lacking any application). Working on this module is more or less of a fun hobby to me, people using it only make it more worthwhile updating!

? I have a function suggestion! Where can I submit it?

! You can reach me by messaging me or replying to this post!

? Do I need credit to use this module in a public project?

! Nope!

More frequently asked questions will be put here.

Output
String
Parameters
1 - number
2 - boolean that toggles AM/PM format
Examples

local module = require(game.ReplicatedStorage.MathAddons)
print(module.time(13.25)) -- using 1 parameter would give you the 24 hour clock, this'll return "13:15"
print(module.time(13.25,true)) -- the second parameter is whether or not you want to use the 24 hour system or 12 hour. This'll return "1:15 PM"

Real Situation
You can convert the time of day in-game with this

Real Situation
A very niche idea but you can make a prime finder with this

local module = require(game.ReplicatedStorage.MathAddons)

Examples

local module = require(game.ReplicatedStorage.MathAddons)
print(module.frac(.25) -- 1/4

You’re making a rank system every few levels they advance to a new rank, in those levels they progress in rank I, rank II, rank III, rank IV…

local module = require(game.ReplicatedStorage.MathAddons)
local rankTable = {'Noob','Okay', 'Good', 'Great', 'Pro', 'Advanced', 'Best', 'God Level'}
local level = 41
local levelsPerRank = 6
player.stats.Rank.Value = rankTable[math.floor(level/levelsPerRank)].. module.roman(level%levelsPerRank)

Imaginary Library

• The goal of this library is to recreate every single math function, but support for input and outputs of imaginary numbers.

This is an ever-growing library, so keep an eye out!
• How will this work?
The Complex Library is separated from the other functions and should be accessed like this

local complex = require(MathAddons).Imaginary

and using the functions is as easy as the parent library

local complex = require(MathAddons).Imaginary
local real,imaginary = complex.add(a,b,c,d) -- (a+bi)+(c+di)

The last parameter is telling the program whether you want it in string form, or to return two numbers

local complex = require(MathAddons).Imaginary
print(complex.add(1,2,3,4,false)) -- since the toggle is false (the default), it will return 4,6
print(complex.add(1,2,3,4,true)) -- this returns a string due to setting to true 4+6i
print(complex.add(1,2,3,4)) -- this will also return 4,6. So that calculating inputs of other functions will be easier

Conversion of Complex Numbers to their Polar Form

More

They give a very sciency proof and explanation of the polar form, let me simplify it
Polar Form - Wikipedia
Polar Form looks like this
where r is the radius of the circle the point is sitting on
and θ is the angle of the line
This is 1+1i plotted on the imaginary axis

The first step is to find the radius of the circle or in other words the length of the line
using the Pythagorean theorem
we can find the length of this line

a and b are both equal to 1 so
= 2
and c =
so the radius of that circle is
and if a circle is drawn, with radius you can see the point sits on that circle

to find the value θ, you need to find how far around the point is on the circle, or whats the degree of this angle

you need to use the arctangent function to find the given angle
the input will be the slope of the line, which is 1 since b/a = 1/1 = 1

so now we have the θ value, you can put it into the form and you get

Purpose
Combine two Complex Numbers
Output
Parameter 5 set to true - String
Parameter 5 set to nil/false - Number, Number

Parameters
1 - Number - a value in (a+bi)
2 - Number - b value in (a+bi)
3 - Bool - Returns a string or two Numbers
Examples

local complex = require(game.ReplicatedStorage.MathAddons).Imaginary
print(complex.complexToPolar(1,1,true)) -- the example shown above gives us that 1+1i in polar form is approximately 1.4142135623730951e^0.7853981633974483i

Real to the power of i

More

I can’t find an explanation of this online, so here we go again
Two rules make the rest easy

applying the first rule

applying the second rule

now you can substitute any value for x to find the complex number

Purpose
find x^i for any value of x
Output
Parameter 5 set to true - String
Parameter 5 set to nil/false - Number, Number

Parameters
1 - Number - x value in x^i
2 - Bool - Returns a string or two Numbers
Examples

local complex = require(game.ReplicatedStorage.MathAddons).Imaginary
print(complex.realToComplex(2,true)) -- returns 0.7692389013639721+0.6389612763136348i

i to the power of a Real

More - Open at your own risk

Here’s an intuitive way i figured this out
here is what we know/the obvious
i^0 = 1
i^1 = i
i^2=-1
i^3=-i
i^4=1
these are also defined by 90-degree rotations on the imaginary axis

to get from 1 to i, you rotate 90 degrees (we’re adults now so we use pi/2)
so associating them with rotations we get
i^0 = 0pi/2
i^1 = pi/2
i^2 = 2pi/2
i^3 = 3pi/2
i^4 = 4pi/2 (or 0)
with this, we can make a unit rate
i^x=x*pi/2
now we can work with fractional values
since we’re working with i by itself, the radius is 1
the last part is to find a way to calculate the point of a power
for this, i used .5, or the square root of i

the point can be thought as legs of a right triangle and the hypotenuse is 1

sin is defined as the ratio of the opposite leg to the hypotenuse, but since the hypotenuse is 1, sin(x) is the length of the opposite side, in other words, to find the y value you get the sine of xpi/2 where x is the power, in the case of the example, x = .5
so the y coordinate = sin(.5pi/2) = sin(pi/4) which is

cosine in this context is defined as the ajecent leg, so the x value is cos(pi/4) =

so the coordinate of that point, or in other words the solution to i^.5 =

Purpose
find x^i for any value of x
Output
Parameter 5 set to true - String
Parameter 5 set to nil/false - Number, Number

Parameters
1 - Number - x value in i^x
2 - Bool - Returns a string or two Numbers
Examples

local complex = require(game.ReplicatedStorage.MathAddons).Imaginary
print(complex.realToComplex(2,true)) -- returns 0.7692389013639721+0.6389612763136348i

Complex Number to a Complex Number

laws of exponents also shows that

so

Output
Parameter 5 set to true - String
Parameter 5 set to nil/false - Number, Number

print(complex.pow(1,1,1,1,true)) -- the example shown above gives us that (1+1i)^(1+i)  is approximately 0.27395725383012104+0.5837007587586147i

Mathematical Constants

• Some important constants (that still have no common use in programming)

Eulers Number

More

e (mathematical constant) - Wikipedia

Purpose
Get the constant e

Proof (Math Rant)

Eulers Constant is calculated 2 ways

Infinite Sums

Using this sum

as k approaches infinity, you get better and better approximations for e, this isn’t what the module uses since this is very performance heavy

Compound Interest

An intuitive example of this would be the Compound Interest Formula

If you start with 1 dollar (P - Principal) and increase it by a rate of 100% (r - Rate) for 1 year (t - Time) n times, as n approaches infinity, you get better estimations for Eulers Constant
Lua is stupid so it comes up with 1 for numbers bigger than 10^15 (probably because lua doesn’t deal with numbers with more than 13 digits, this isn’t confirmed though)

The Final Way

Since solving it mathematically doesn’t work, I looked up a million digits of e and put them into the code

Examples

local module = require(game.ReplicatedStorage.MathAddons)
print(module.e) -- This is approximately 2.71828182846

This value is approximately:

Pi

More

Pi - Wikipedia

(This is just 162 digits but here you go)
Purpose
Get pi

Proof

Using Infinite Sums, you can use this formula

as k approaches infinity, the value of the sum gets closer to pi. This (thankfully) isn’t what the module uses since its a performance issue

Examples

local module = require(game.ReplicatedStorage.MathAddons)
print(module.pi) -- This is about 3.14159265358979323846...

This value is approximately:

Phi / The Golden Ratio

More

Golden ratio - Wikipedia

Purpose
Get the Golden Ratio

Proof

The definition of Phi is it being

split the first fraction into

simplify

b/a is the reciprocal of a/b, so they can be written as

using the quadratic formula to find the positive solution, you end up with

which is the golden ratio

Examples

local module = require(game.ReplicatedStorage.MathAddons)
print(module.phi) -- This is approximately 1.6180339887498948482045868343656381177203091798057628621354486227

This is my first resource so I hope it helps
I know this module is pretty easy to make in terms of the simplicity in (some of) the functions, but I thought it would be kinda cool to have an add-on to the default math functions. More things will come in the future so I recommend requiring the module by 7066695577

I see interesting saves a lot of space.

D0RYU · July 9, 2021, 12:16am

you do realize Round and Square Root already exist, right?

Squiegy · July 9, 2021, 12:18am

I didnt see sqrt existed, but theres only math.ceil and math.floor

D0RYU · July 9, 2021, 12:18am

no math.round exists, I have the screenshots

Squiegy · July 9, 2021, 12:19am

I dont see it

RecanValor · July 9, 2021, 12:20am

It exists.

I did not know it existed either, as last time I checked it did not exist.

D0RYU · July 9, 2021, 12:22am

not all things are auto put into the scripts, roblox and lua have documentations for a reason!

steven4547466 · July 9, 2021, 12:22am

It’s just not autocompleteable.

Squiegy · July 9, 2021, 12:23am

Oh okay thanks for the help

Jerrythepancakesmith · July 9, 2021, 12:26am

ya you shouldnt rely too much on roblox suggestion cause some of the api dont show.

Squiegy · July 9, 2021, 12:28am

I still hope im not the only one who thinks thats a bit dumb to have to look through the wiki just to find if something exists

sjr04 · July 9, 2021, 1:41am

Yeah, a lot of these functions are trivial to implement or already exist. How does compete with, for example, mine ? (you should also consider posting the code in a github repo so it can be easily seen by users who may not have computer access and so others can contribute to it)

D0RYU · July 9, 2021, 2:17am

as of right now this MathService has only 6 functions, so it doesn’t have as much as yours

Bloxxy213_DVL · July 9, 2021, 6:24am

Kinda useless, exists for months (Or years?). The second argument may be usefull

Everyone can do it without any module.

local coinflip = function()
   return math.random(1,2) == 1
end

As the last one, easy.

local fact = function(num)
   local EndNum = num
   for i = num-1,1,-1 do
         EndNum *= i
   end
   return EndNum
end

This may be useful, but what about modules that are better? For example from 1000 to 1k?

Easy.

local Int = function(num)
    return string.find(tostring(num),"%p") and true or false
end

Squiegy · July 9, 2021, 12:51pm

I realized that most of them are easy and replaceable
I think its easier if you need one of the functions you can save a few lines. But i see where you’re coming from

D0RYU · July 9, 2021, 1:23pm

couldn’t you literally do this

local Int = function(num)
    return tonumber(num) % 1 == 0
end

Bloxxy213_DVL · July 9, 2021, 1:24pm

Oh, oops. I was working on a project with many strings ;/

TESLAC0IL · July 9, 2021, 2:52pm

Just to let you know, math.round exists but is for some reason not found in the autocomplete.

ItsPlasmaRBLX · July 9, 2021, 11:22pm

I’ve been waiting for something like this! Is it possible to add a better math.round that has decimals and is configurable?

Example:

-- the first argument is the amount of decimals
-- in the 2nd argument is the number set.
MathService.random(2, {2, 4}) --- 3.21
MathService.random(4, {5, 10}) --- 7.3842

Here are a few more functions that have no practical use in programming

• The goal of this library is to recreate every single math function, but support for input and outputs of imaginary numbers.

• Some important constants (that still have no common use in programming)
