How to convert an integer (int) to a floating point number (float64) in Go?

Hello everyone! I'm just starting to learn Go after Python and encountered a problem with type conversion. In Python, I'm used to floating point numbers and integers mixing easily in expressions, but in Go everything is strict.

I have a simple arithmetic mean calculator. I get a sum of integers (int) and a count of elements (also int). I need to calculate the average, which obviously can be fractional. But the compiler complains when I try to divide int by int and get a float.

    fmt.Println(avg)
}

I understand that in Go, integer division d
