Category: Best Practices

Description

Simple operations such as math.Pow with a small number can be simplified. Simplification should be used when applicable.

Non-Compliant Code Examples

func main () {
    foo := math.Pow(x, 0)
    foo := math.Pow(x, 1)
    foo := math.Pow(x, 2)
    foo := math.Pow(x, 3)
    foo := math.Pow(x, 4)
    foo := math.Pow(x, 010)
}

Compliant Code Examples

func main () {
    foo := 1
    foo := x
    foo := x*x
    foo := x*x*x
    foo := math.Pow(x, 4)
    foo := math.Pow(x, 010)
}
