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?

One advantage is that it makes the value explicit so anyone reading the code irregardless of their familiarity with Go will know it will be zero.

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.
