What are the division operators in golang?

Operators include: 1. "/" operator, which can divide two operands, the syntax is "operand 1 / operand 2"; 2. "%" modulo (remainder) Operator can perform division operation on two operands and return the remainder. The syntax is "operand 1 % operand 2"; 3. "/=" division assignment operator, which performs division operation first and then assigns the result to The variable on the left side of the operator; 4. The "%" remainder assignment operator performs the remainder operation first, and then assigns the result to the variable on the left side of the operator.

The operating environment of this tutorial: Windows 7 system, GO version 1.18, Dell G3 computer.

Operator is a special symbol used to represent data operations, assignments and comparisons.

The operators that can perform division operations in golang are:

"/" and "%" are arithmetic operators, a symbol used to perform arithmetic operations on numbers (literal or variables).

"/" is the division operator
"%" is the modulo (remainder) operator
Notes when using

For the division sign /, its integer division and decimal division are different; when dividing between integers, only the integer part is retained And discard the decimal part. No rounding etc. will be done. Example: x:=50/9 The result is 5
. When taking the modulo of a number, it can be equivalent to a%b=a-a/b*b
Example

package main

import "fmt"

func main() {

   var a int = 21
   var b int = 10
   var c int

   c = a / b
   fmt.Printf("除法运算符 - c 的值为 %d\n", c )
   c = a % b
   fmt.Printf("取余运算符 - c 的值为 %d\n", c )
}

##"/=" and "%=" operator

"/=

%=" are expanded assignment operators, which combine = with other operators (including arithmetic operators, bitwise operators and logical operators) and expand them into functions More powerful assignment operators.

• “%=” first Perform a modulo operation and assign the result to the variable on the left side of the operator

• Example:

package main

import "fmt"

func main() {
   var a int = 21
   var c int =3
   a /=  c
   fmt.Printf("a 值为 = %d\n", a )
	
   var b int = 9
   var d int =2
   b %=  d
   fmt.Printf("b 值为 = %d\n", b )
