Master the remainder operation in go

Use the % operator in the Go language to perform remainder operations. The syntax is: result := dividend % divisor. This operation returns the remainder of the division of two numbers. Note that an error is raised when the divisor is 0 and the sign of the result is the same as the divisor.

Remainder operation in Go language

The remainder operation is a very useful operation in programming, it can return The remainder after dividing two numbers. In Go language, you can use the % operator to perform the remainder operation. The syntax is as follows:

result := dividend % divisor

Among them, dividend is the number to be divided, divisor is the number to be divided, result is the remainder the result of.

Practical Case

The following is a practical case of using remainder operation in Go language:

package main

import "fmt"

func main() {
    // 计算10除以3的余数
    result := 10 % 3

    // 打印结果
    fmt.Println("10除以3的余数为：", result) // 输出：1
}

Notes

• When divisor is 0, the remainder operation will cause a divide-by-zero error. To avoid this, you should always check if divisor is 0 before performing a remainder operation.
• The result of the remainder operation is always of the same sign as divisor. For example, (-10) % 3 will return -1, while 10 % (-3) will return 1.
