Converting a float number into an integer number in Golang

Problem Solution:

In this program, we will convert 64-bit float number into 64-bit integer number using the int64() function and print the result on the console screen.

Program/Source Code:

The source code to convert float number into integer number is given below. The given program is compiled and executed successfully.

Golang code to convert a float number into an integer number

// Golang program to convert float number
// into an integer number

package main

import "fmt"

func main() {
	var floatNum float64 = 32.17
	var intNum int64 = 0

	intNum = int64(floatNum)
	fmt.Println("Num : ", intNum)
}

Output:

Num :  32

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 fmt package that includes the files of package fmt then we can use a function related to the fmt package.

In the main() function, we two variables floatNum, intNum that are initialized with 32.17, 0 respectively.

After that, we converted the floatNum variable into an integer number and assigned it to the intNum variable using the int64() function, and print the result on the console screen.
