-- TYPE MISMATCH ---------------------------------------------
repl-temp-000.elm
The left argument of (/) is causing a type mismatch.
8| t.val / 0
^^^^^
(/) is expecting the left argument to be a:
Float
But the left argument is:
Int
Hint: Elm does not automatically convert between Ints and Floats. Use
`toFloat`
and `round` to do specific conversions.
<http://package.elm-lang.org/packages/elm-lang/core/latest/Basics#toFloat>
Hint: The (/) operator is specifically for floating point division, and
(//) is
for integer division. You may need to do some conversions between ints and
floats to get both arguments matching the division operator you want.

So for integer division by zero, it simply returns zero!
