How to Get Uint32 Type Random Number in Golang?
• Last Updated : 26 Mar, 2020

Go language provides inbuilt support for generating random numbers of the specified type with the help of a math/rand package. This package implements pseudo-random number generators. These random numbers are generated by a source and this source produces a deterministic sequence of values every time when the program run. And if you want to random numbers for security-sensitive work, then use the crypto/rand package.

You are allowed to generate a pseudo-random number of a 32-bit integer as an uint32 type from the default source with the help of the Uint32() function provided by the math/rand package. So, you need to add a math/rand package in your program with the help of the import keyword to access the Uint32() function.

Syntax:

`func Uint32() uint32`

Let us discuss this concept with the help of the given examples:

Example 1:

 `// Golang program to illustrate``// how to get a random number``package main`` ` `import (``    ``"fmt"``    ``"math/rand"``)`` ` `// Main function``func main() {`` ` `    ``// Finding random numbers``    ``// Using Uint32() function``    ``res_1 := ``rand``.Uint32()``    ``res_2 := ``rand``.Uint32()``    ``res_3 := ``rand``.Uint32()`` ` `    ``// Displaying the result``    ``fmt.Println(``"Random Number 1: "``, res_1)``    ``fmt.Println(``"Random Number 2: "``, res_2)``    ``fmt.Println(``"Random Number 3: "``, res_3)``}`

Output:

```Random Number 1:  2596996162
Random Number 2:  4039455774
Random Number 3:  2854263694
```

Example 2:

 `// Golang program to illustrate the``// use of the random numbers``package main`` ` `import (``    ``"fmt"``    ``"math/rand"``)`` ` `// Function``func uint32random(value_1, value_2 uint32) uint32 {``    ``return` `value_1 + value_2 + ``rand``.Uint32()`` ` `}`` ` `// Main function``func main() {`` ` `    ``// Getting result from uint32random() function``    ``res1 := uint32random(10, 3)``    ``res2 := uint32random(44, 59)``    ``res3 := uint32random(130, 50)`` ` `    ``// Displaying results``    ``fmt.Println(``"Result 1: "``, res1)``    ``fmt.Println(``"Result 2: "``, res2)``    ``fmt.Println(``"Result 3: "``, res3)``}`

Output:

```Result 1:  2596996175
Result 2:  4039455877
Result 3:  2854263874
```
