The author used:

    sum := float32(0)

Over Go's zero-value default initialization e.g.

    var sum float32

A nit stylistically but wondering if there was a good reason to do so?

i do the same because i find the var keyword ugly

Sure, I understand that from the POV of making your code explicit. Personally I have always tended towards, for example:

    var x string

when initializing empty (zero-value) vars, versus:

    x := "hello"

when initializing variables that should hold an initial value.

To me as a Go programmer at least, this is more obvious and intuitive as to the intent of the declaration.
