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),
)
}
why the output is
27 >= 20
9 20
but not
9
27 >= 20 20
the code for your expected result is
func main(){
fmt.Println(pow(3, 2, 10))
fmt.Println(pow(3, 3, 20))
}
After all "pow" functions in "fmt.Println" are called, "fmt.Println" prints the results of pows
Because both calls to pow(..) are evaluated before fmt.Println() as they are used as arguments to it.
What you expected would have been the output of
func main() {
fmt.Println(pow(3, 2, 10))
fmt.Println(pow(3, 3, 20))
}
