How to divide an integer returned from a function by a double value?

Question

Given this function:

func anInt() -> Int {
  return 5
}

This doesn't work:

anInt() / Double(2)
>> ERROR: Could not find an overload for '/' that accepts the supplied arguments

However this works:

5 / Double(2)
>> 2.5

Answer 1

When you call anInt() / Double(2) the compiler knows you are trying divide an Int by a Double and doesn't allow that, but when you call 5 / Double(2), it can infer the type of 5 as a Double since you are dividing it by a Double.
