bits.Rem() Function in Golang with Examples

Go language provides inbuilt support for bits to implement bit counting and manipulation functions for the predeclared unsigned integer types with the help of bits package. This package provides Rem() function which is used to find the remainder of (h, l) divided by a. This function will panics if a == 0 (division by zero) and it doesn’t panic if quotient overflow. To access Rem() function you need to add a math/bits package in your program with the help of the import keyword.

Syntax:

func Rem(h, l, a uint) uint

Parameters: This function takes three parameters of uint type, i.e., h, l, and a.

Return Value: This function returns the remainder of (h, l) divided by a.

Example 1:

// Golang program to illustrate bits.Rem() Function
package main

import (
    "fmt"
    "math/bits"
)

// Main function
func main() {

    // Finding remainder
    // Using Rem() function
    r := bits.Rem(8, 9, 3)
    fmt.Println("Remainder:", r)

}

Output:

Remainder: 2

Example 2 :

// Golang program to illustrate bits.Rem() Function
package main

import (
    "fmt"
    "math/bits"
)

// Main function
func main() {

    // Finding remainder
    // Using Rem() function
    var h, l, a uint = 3, 5, 2
    r := bits.Rem(h, l, a)
    fmt.Println("Number 1:", h)
    fmt.Println("Number 2:", l)
    fmt.Println("Number 3:", a)
    fmt.Println("Remainder:", r)

}

Output:

Number 1: 3
Number 2: 5
Number 3: 2
Remainder: 1
