Generating the random number of float types in Golang

Problem Solution:

Here, we will generate random numbers of float types between and print the result on the console screen.

Program/Source Code:

The source code to generate the random number of a float type is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

Golang code to generate the random number of float types

// Golang program to generate the
// random number of float types

package main

import "math/rand"
import "fmt"

// Entry point for the program
func main() {
	fmt.Println("32-bit float number: ", rand.Float32())
	fmt.Println("64-bit float number: ", rand.Float64())
}

Output:

32-bit float number:  0.6046603
64-bit float number:  0.9405090880450124

Explanation:

In the above program, we declare the package main. The main package is used to tell the Go language compiler that the package must be compiled and produced the executable file. Here, we imported the required packages to predefined functions.

In the main() function, we generated 32-bit and 64-bit random float numbers. After that, we printed the result on the console screen.
