Go Operators

How it works

Arithmetic operators work on compatible numeric values. Assignment operators update a variable. Comparisons return bool, and logical operators combine bool values. Bitwise operators apply to integers. Go has no general ternary conditional operator; a small if statement is often clearer.

Run this Go example

Install Go separately from the official Go downloads and check go version in a new terminal. The reviewed baseline is Go 1.27.3 on Windows amd64; the authored syntax and standard-library APIs require Go 1.22 or newer. Save the complete source below as operators.go in a learning folder, then run go run operators.go from that folder. These examples use only the standard library.

Bhylu has no Go browser runner. Apache, MySQL, PHP and the JavaScript or Python playground are not required to run these files. File examples own a temporary directory; HTTP client examples create an ephemeral loopback server and close it. They do not contact an external API.

Download the complete operators.go · Download all source files with hash checks

For the optional collection download, save download-examples.mjs in a new learning folder and run node download-examples.mjs. A local preview uses node download-examples.mjs http://127.0.0.1:8000/examples/go/. The downloader refuses an existing bhylu-go-examples folder and installs or executes no Go code.

Example

package main

import (
	"fmt"
)

func main() {
	free := 12 - 5
	free -= 2
	canAccept := free >= 3 && free <= 12
	const fragile = 1 << 0
	const priority = 1 << 1
	flags := fragile | priority
	fmt.Println(free, canAccept, flags&priority != 0)
}

Expected result

5 true true

The count reaches five after two reservations. The bitwise OR combines flags; AND checks whether the priority bit is present. Parentheses can clarify a mixed expression even when precedence already defines it.
