I have most of them marked down in my bundle library under expressions.
But also I get most of my formulas from the Math Haxe documentation.

There are many expressions and types that you can use for what you need. It’s a bit of a mix of coding and math, actually. Most expressions I do come down to formulas, but the most helpful tool I’ve used are if statements to separate answers depending on the inputs.
If statements are Number > Number ? True : False
The “%” is actually a math sign in coding called “Modulo” or the “Remainder” sign.
It takes a value, divides it, and spits out the remainder.
For example: 43 % 10 = 3 or 43 / 10 = 4 with a remainder of 3.
Another example is A % 2 will spit out if it’s even or odd.
The only bad thing about Modulo is that if the value is equal on both sides, Modulo will spit out 0.
So 15 % 5 = 0 instead of 5. So what I do is ((5-1) % 5) +1 to get the better value.
But overall, my greatest achievement with expressions is writing over 150 lines of Haxe code for the ease bundle example, somewhat shown here.
