Lua dsk - Please give me some feedback and function ideas to add

For the past few days I have been working on my own modded Lua (if you didnt know, roblox uses Luau which is a modded version of Lua). So far, I have completed the following functions

  1. randomNumber(integer, integer) – replaces math.random(integer, integer)
  2. returnSquareRoot(#) – replaces math.sqrt
  3. floor(#) – removes all decimals from a number, replaces math.floor and math.ceil
  4. greaterThan(arg1, arg2) – replaces ‘if arg1 > arg2 then local var = true return end’
  5. lessThan(arg1, arg2) – replaces ‘if arg1 < arg2 then local var = true return end’
  6. equalTo(arg1, arg2) – replaces ‘if arg1 == arg2 then local var = true return end’
  7. getChild(checking, lookingfor) – replaces :FindFirstChild() and :WaitForChild()

I tried to minimize the amount of premade Luau functions I used because using them would be pointless, but heres a list of what I used so far

  1. random.new():NextNumber(#,#)

here is a Link to the module, If i could get some feedback on my progress that would be amazing. I also need some ideas on functions I should add, because I dont want to just remake Luau functions. Thank you!!!

– there is a script inside the module with examples on how to use the functions –

I just want to make it clear that im not only going to remake Luau functions, I will also make functions such as

returnMatrix(a, b, c, d)

which would save people from doing huge amounts of math, so please give me some function ideas!
