let's get going - Syntax Basics - Conversons, math operations
Head First Go、 Jay McGavren(著)、O’Reilly Media)の Chapter 1(let’s get going - Syntax Basics)、p.24(Exercise)の解答を求めてみる。
コード
sample.go
package main
import "fmt"
func main() {
price := 100
fmt.Println("Price is", price, "dollars.")
taxRate := 0.08
tax := float64(price) * taxRate
fmt.Println("Tax is", tax, "dollars.")
total := float64(price) + tax
fmt.Println("Total cost is", total, "dollars.")
availableFunds := 120
fmt.Println(availableFunds, "dollars available.")
fmt.Println("Within budget?", total <= float64(availableFunds))
}
入出力結果(Terminal, Zsh)
% go run ./sample.go
Price is 100 dollars.
Tax is 8 dollars.
Total cost is 108 dollars.
120 dollars available.
Within budget? true
