Hello, I would like to know which are the most used Math functions and constants according to your experiences and which ones you recommend to learn and use.

it’s depends. for magnitude most people use math.abs, so this thing turns number with minus at the start to plus (we don’t see this plus of course). i saw alot of calculations with math.pi, this is very useful constant number. i would name my list of others useful things:
- math.floor
- math.ceil
- math.clamp
- math.random
- math.deg, rad
- math.sin, cos, tan
i think thats the most useful math functions.

I use the most:
- math.cos returns the cosine of the angle given in radians
- math.acos returns the inverse cosine of the number
- math.sin returns the sine of the angle given in radians
- math.asin returns the inverse sine of the number
- math.floor returns the largest integer smaller than or equal to x
- math.ceil returns the smallest integer larger than or equal to x
- math.abs returns the absolute value of the number (basically the distance between 0 and the number)
- math.max given a & b numbers, it returns the greatest
- math.min given a & b numbers, it returns the smallest
-
math.rad returns x, but in radians (i also use
angle/180*3.1415926535898) -
math.deg returns x, but in degrees (i also use
angle/3.1415926535898*180) - math.pi returns pi
- tau (math.pi*2) this isn’t a math function, but a constant that may be useful
I think they aren’t that hard to learn, and they are useful.

I actually just used math.cos/sine to rotate a 2D vector for my wall builder.
The post and code is here: Wall Builder | Smoothening Algorithm - #2 by MrNicNac
The red vector is the direction to the next blue square. Then, using math.cos/math.sine, I rotated the vector on the XZ plane 45 degrees (yellow vectors)
