Fancy Commands for Counters, Math, & Coin Toss

Random number: $(eval var min = Number(decodeURIComponent('$(querystring $(1))')); var max = Number(decodeURIComponent('$(querystring $(2))')); var result; if (isNaN(min) || isNaN(max)) { result = "Type '!random x y', where x & y are integers."; } else { Math.floor(Math.random() * (max - min + 1) + min) } )

Chooses an integer between 1 & 10, including both 1 & 10. This also works if you choose 1 & 100, 1 & 2, -56 & 1234, whatever you'd like!

Coin toss
!cointoss
🪙 $(eval var sides = ['Heads!','Tails!']; sides[Math.floor(Math.random() * 2)])

This is a simple adjustment of the !8ball command to display a coin toss instead. Uses a coin emoji!

Die roll
!die
🎲 $(eval var die = ['1','2','3','4','5','6']; die[Math.floor(Math.random() * 6)])

Same as above but for the roll of a die.

Dice roll
!dice
🎲🎲 $(eval var d1 = ['1','2','3','4','5','6']; var d2 = ['1','2','3','4','5','6']; d1 = d1[Math.floor(Math.random() * 6)]; d2 = d2[Math.floor(Math.random() * 6)]; var dice = Number(d1) + Number(d2); dice = "You rolled a " + dice + "!")

2 dice with possible rolls of 2–12 & the same probabilities you'd expect from real dice.

Math stuff
Preface: I won't really explain the next ones too much, but the command tells you the syntax. Unfortunately, fractions don't work, but positive, negative, & decimals work just fine! The long complicated commands are to ensure security, as using $(1) in JavaScript is a no-no. I also wanted to tell the user how to use the command without flooding chat every time someone uses it correctly.
All of these commands are available to everyone & have no alias. Just need to copy/paste twice each.

Addition/subtraction (with negative numbers)
!add

Sum: $(eval var x = Number(decodeURIComponent('$(querystring $(1))')); var y = Number(decodeURIComponent('$(querystring $(2))')); var result; if (isNaN(x) || isNaN(y)) { result = "Type '!add x y', where x & y are integers or decimals."; } else { x + y } )

Multiplication
!mult
Product: $(eval var x = Number(decodeURIComponent('$(querystring $(1))')); var y = Number(decodeURIComponent('$(querystring $(2))')); var result; if (isNaN(x) || isNaN(y)) { result = "Type '!mult x y', where x & y are integers or decimals."; } else { x * y } )

Division
!div
Quotient: $(eval var x = Number(decodeURIComponent('$(querystring $(1))')); var y = Number(decodeURIComponent('$(querystring $(2))')); var result; if (isNaN(x) || isNaN(y)) { result = "Type '!div x y', where x & y are integers or decimals."; } else { x / y } )

Exponentiation
!exp
Power: $(eval var x = Number(decodeURIComponent('$(querystring $(1))')); var y = Number(decodeURIComponent('$(querystring $(2))')); var result; if (isNaN(x) || isNaN(y)) { result = "Type '!exp x y', where x & y are integers or decimals."; } else { Math.pow(x, y) } )

Hypotenuse for 2 sides
!hypot
2D Hypotenuse: $(eval var x = Number(decodeURIComponent('$(querystring $(1))')); var y = Number(decodeURIComponent('$(querystring $(2))')); var result; if (isNaN(x) || isNaN(y)) { result = "Type '!hypot x y', where x & y are integers or decimals."; } else { Math.hypot(x, y) } )

Hypotenuse for 3 sides
!hypot3

3D Hypotenuse: $(eval var x = Number(decodeURIComponent('$(querystring $(1))')); var y = Number(decodeURIComponent('$(querystring $(2))')); var z = Number(decodeURIComponent('$(querystring $(2))')); var result; if (isNaN(x) || isNaN(y) || isNaN(z)) { result = "Type '!hypot3 x y z', where x, y, & z are integers or decimals."; } else { Math.hypot(x, y, z) } )

More mathy stuff such as trigonometric functions & logarithms can be found at the JavaScript docs
I make use of the Number() function to ensure the inputs are the right type for JavaScript to do its thing; non-formated numbers like fractions won't work & will result in null & NaN. At the top of the link you'll also find constants like e, pi, log(10), & sqrt(2). Fun stuff!

I was unfortunately not able to figure out how to use a single command as a calculator, allowing "4 + 6" & "7 * 12" as inputs. Thus, I had to create separate commands for arithmetic. Subtraction I ignored as you can just use "!add 5 -2" to the same effect as "!sub 5 2".

In the coming days, I want to create commands that take userlevel into account for the response. I also want to scroll through the forums for unanswered questions from years past to see if I can work my magic, but that may be overambitious. If you have any more complex commands you think would be helpful for the community, I'd like to make this a resource of sorts.

Great stuff!
However, I'd suggest editing your post so it's formatted more clearly, code blocks are necessary for example. If you don't know how to format your post, I suggest this tutorial, it'll only take you about 10 minutes.

Formatted according to the tutorial. Thanks.
