Not equals to (number to number)

Hi, I was wondering is it possible to make variable comparison to a range of numbers in a simple way, something like if X is not equal to 16 to 20 (which are 16,17,18,19,20) then do something. Would be so nice

You can just do something like this:
Meaning it will be true as long as it is not between these two numbers. Seems a bit silly to add a special function for this.

I usually put the two conditions in a way that makes the numbers increase, from lower to upper:
if you *really* need a function, this should do:
Code: Select all
function between(x,min,max)
return min <= x and x <= max
end
Usage:

Wont that be trur if x is larger than 16 OR less than 20 meaning that anything would return true
Eg. 5<20 therefore continue if statement

True.

Oh, you know what I meant.

Oh, I read this incorrectly. OP wanted to check that x is
not in the range. Well, once you have a function, doing the contrary is easy:
If you want to write the whole code with no functions, I sill think it helps to have the numbers in order. I'd do something like this:
But for the negation, I think that "not between" is more clear.

Actually, what OP specified was not inrange(x, 16, 20) - between(x, 16, 20) implies exclusion of the range limits, 16 and 20.
So :
Code: Select all
function inrange(x, lower, upper)
return x >= lower and x <= upper
end
if not inrange(x, 16, 20) then end
You were closer the first time
