Why is overloading a function with different types not possible:

fn sum(num1: Int, num2: Int) -> int: return num1 + num2 fn sum(num1: Float, num2: Float) -> Float: return num1 + num2

Your code is incorrect, there is no int, only Int and there's Float32 not Float function overloading is possible.

fn sum(lhs: Int, rhs: Int) -> Int:
    return lhs + rhs
fn sum(lhs: Float32, rhs: Float32) -> Float32:
    return lhs + rhs

fn main():
    let float: Float32 = 1
    let int: Int = 2
    
    print(sum(float, float))
    print(sum(int, int))

fn sum(lhs: Int, rhs: Int) -> Int:
    return lhs + rhs
fn sum(lhs: Float32, rhs: Float32) -> Float32:
    return lhs + rhs

fn main():
    let float: Float32 = 1
    let int: Int = 2
    
    print(sum(float, float))
    print(sum(int, int))

will print
