bits.Rem64() Function in Golang with Examples
• Last Updated : 28 Apr, 2020

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 Rem64() 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 Rem64() function you need to add a math/bits package in your program with the help of the import keyword.

Syntax:

`func Rem64(h, l, a uint64) uint64`

Parameters: This function takes three parameters of uint64 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.Rem64() Function``package main`` ` `import (``    ``"fmt"``    ``"math/bits"``)`` ` `// Main function``func main() {`` ` `    ``// Finding the remainder``    ``// Using Rem64() function``    ``var h, l, a uint64 = 3, 5, 2``    ``r := bits.Rem64(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
```

Example 2 :

 `// Golang program to illustrate bits.Rem64() Function``package main`` ` `import (``    ``"fmt"``    ``"math/bits"``)`` ` `// Main function``func main() {`` ` `    ``// Finding remainder``    ``// Using Rem64() function``    ``r := bits.Rem64(8, 9, 3)``    ``fmt.Println(``"Remainder:"``, r)``}`

Output:

`Remainder: 2`
