New to GO- how it handles float precision 0.4 + 0.2 is 0.6

Getting Help

Go’s float32 and float64 types follow IEEE 754, just like many other languages. This means that it will be subject to the same limitations.

package main

import "fmt"

func main() {
	fmt.Printf("%T %T\n", 0.2, 0.2+0.4) // float64 float64

	fmt.Println(0.2 + 0.4)                   // 0.6
	fmt.Println(float32(0.2) + float32(0.4)) // 0.6
	fmt.Println(float64(0.2) + float64(0.4)) // 0.6000000000000001
}

Regarding fmt.Println(0.2 + 0.4), the expression contains only literal constants and as such will be evaluated at compile time rather than runtime.
