package main
import "fmt"
func main() {
// when an integer and a float value used together
// in an expression, the result always becomes
// a float value
fmt.Println(8 * -4.0) // -32.0 not -32
// two integer values result in an integer value
fmt.Println(-4 / 2)
// remainder operator
// it can only used with integers
fmt.Println(5 % 2)
// fmt.Println(5.0 % 2) // wrong
// addition operators
fmt.Println(1 + 2.5)
fmt.Println(2 - 3)
// negation operator
fmt.Println(-(-2))
fmt.Println(- -2) // this also works
