Code:
function math.clamp(value, min, max)
  if value < min then
    value = min
  elseif value > max then
    value = max
  end
  return value
end


function that compares value with min and max and replace it with min or max and return the value

Alternative:
Code:

function clamp(n, low, high)
  return math.min(math.max(n, low), high)
end

I don't think this is the right explanation for math.clamp, at least you try to give a more specific explanation to the readers.

What is math.clamp in Lua?. Is it useful or no and how itís working?.



Code:
math.clamp(x, min, max) clamps a number (x) between min and max. If itís greater than max, itíll return max. If itís lower than min, itíll return min. Otherwise, itíll return x. You couldíve just checked the wiki, though.


https://developer.roblox.com/en-us/api-reference/lua-docs/math

or

Code:
ďIt takes 3 values. X, min and max. If X is in the range between min and max it returns X. If X is lower than min it returns min and if X is higher than max it returns max.

This can be useful for tons of applications, but a good example would be constraining rotation on an axis. If you want a player to control the rotation of a brick on the Y axis but only in a 90 degree window you could clamp itís total rotation.Ē
