How would I make it so I get something every something

[butterpilot123 (Butter)]

So for example if I wanted to get 10 diamonds per every 100 coins how would I do that without having to manually type every multiple of 100. Thanks

If coins ~= 0 and coins % 100 == 0 then 
-- give diamons 
end

or

diamonds = math.floor(coins / 100) * 10
