Lua math - whole numbers

Hey I need a program to know if a number is devisible by 3 so I need to know how to get a computer to detect if an answer is a whole number eg. 24/3=8 so true. 13/3=4.33333333333 so false

if math.fmod(7,3) == 0 then
print("there is no remainder")
else
print("there is a remainder")
end

this can tell you if it divided by three correctly alter the numbers in the math.fmod() section and watch the results. if it divided it will return 0 if not it will return something else

Just a side note, math.fmod can be replaced with the % sign, in which the above example can be performed as such:

if 7%3 == 0 then
  print("there is no remainder")
else
  print("there is a remainder")
end
