Can somebody help me understand this?
function checkEven(number)
local real_Number = tonumber(number)
if real_Number then -- if can be a nuber then
if (number%2) then
return true
else
return false
end
end
end
see how he changed the value 'number' from a string into a number, how did he create the value called 'number' because I dont see how he did.
Also if by any change it has to do with him putting it in the parentheses how did he give it a number value???

simplified function: function even(n)n=tonumber(n)return n and n%2==0 end 1waffle1 2908 — 8y

--"number" is a parameter of the function. If you call the function
--with a value to fill that parameter, then "number" will be that value.
--The two chunks of code below are equivalent.
function checkEven(number)
local real_Number = tonumber(number)
if real_Number then
if number % 2 == 0 then
return true
else
return false
end
end
end
print(checkEven(5))
number = 5
local real_Number = tonumber(number)
if real_Number then
if number % 2 == 0 then
print(true)
else
print(false)
end
end
