Go Fundamentals

Operators

Context

Section titled “Context”

Go provides operators similar to C, with a few specifics.

Categories

Section titled “Categories”
  • Arithmetic: + - * / %
  • Comparison: == != < <= > >=
  • Logical: && || !
  • Bitwise: & | ^ &^ (AND NOT) << >>
  • Assignment: = += -= *= /= %= &= |= ^= <<= >>=

Example

Section titled “Example”

Use different operators.

Code example

Section titled “Code example”
package main


import "fmt"


func main() {
    a, b := 10, 3
    fmt.Println("Addition:", a+b)
    fmt.Println("Integer division:", a/b)
    fmt.Println("Remainder:", a%b)


    // Logical operators
    x, y := true, false
    fmt.Println("x && y:", x && y)
    fmt.Println("x || y:", x || y)


    // Bitwise
    c, d := 0b1100, 0b1010
    fmt.Printf("c & d = %b\n", c&d)   // 1000
    fmt.Printf("c | d = %b\n", c|d)   // 1110
    fmt.Printf("c ^ d = %b\n", c^d)   // 0110
    fmt.Printf("c &^ d = %b\n", c&^d) // 0100
    fmt.Printf("c << 1 = %b\n", c<<1) // 11000
}

Output

Section titled “Output”
Terminal window
Addition: 13
Integer division: 3
Remainder: 1
x && y: false
x || y: true
c & d = 1000
c | d = 1110
c ^ d = 110
c &^ d = 100
c << 1 = 11000
