You do not need to convert the string into a slice of bytes to use Write, you can just use the string directly.

Non-Compliant Code Examples

package main

import (
	"fmt"
	"math"
)

func main() {
	n := 5.0
	aNaN := math.NaN()
	// This case cannot be caught with current capabilities
	if n == aNaN {
		fmt.Println("hello")
	} else if n > math.NaN() {
		fmt.Println("hi")
	}

	fmt.Println("goodbye")
}
