I'm taking 'A Tour of GO' tutorial about Golang and this code:
package main
import (
"fmt"
"math"
)
func pow(x, n, lim float64) float64 {
if v := math.Pow(x, n); v < lim {
return v
} else {
fmt.Printf("%g >= %g
", v, lim)
}
// can't use v here, though
return lim
}
func main() {
fmt.Println(
pow(3, 2, 10),
pow(3, 3, 20),
)
}
would print "27 >= 20 9 20".
I'm rather confused why it's not "9 27 >= 20 20"
Shouldn't the first call to pow(3,2,10) return 9, print it, then call pow(3,3,20) and print the rest?
