Hi @wdantuma :slight_smile:! In Go if you to desire layout properly a float number with a particular variety of decimals, you require to utilize %. Nf where N is the variety of figures you desire.
In your instance modification:

with fmt.Printf("%.1 fn", c) The formatter % g stands for the float number with its optimum variety of considerable figures, as well as in your instance you’re utilizing 2 float64 so Go fills up all the appropriate 14 figures instantly

That’s simply drift …

If you require exact outcomes, simply do not utilize drifts.
