If I have a Float value and I want a Int to use elsewhere how do I make that conversion?

Elm makes it very easy to convert between values!
(Note: Because Elm is functional and all variables are immutable, the value is not actually converted, rather a new equivalent value is created.)
All you have to do is choose what you want to do with the decimals!
Round do the nearest integer with round
1.5 |> round -- 2 : Int
Round up with ceiling
1.5 |> ceiling -- 2 : Int
Round down with floor
1.5 |> floor -- 1 : Int
Ignore the deimals with truncate
1.5 |> truncate -- 1 : Int
Converting back is just as easy using toFloat
1 |> toFloat -- 1.0 : Float
