    `exp` `log` `pow` and `ln` should have `Double` as input. What I was thinking is, we should
add some extra `type coercion` rules and add an `cast` when we can do it safely(when an expression
is asking a `Double` but we provide a `Int`), for example, `Byte` to `Double`, `Long` to `Double`
and so on, and rewrite the expression as `pow(cast(x, Double))`
