Here, We will learn how to get the integer value of number in go. We can get it by using Trunc() function in math package in go golang.
Function prototype:
func Trunc(x float64) float64
Return value:
Trunc() function in math package returns
the integer value of x.
Example with code:
package main
import (
"fmt"
"math"
)
func main() {
no := math.Trunc(1.2)
fmt.Println(no)
no = math.Trunc(-2.7)
fmt.Println(no)
no = math.Trunc(0.0)
fmt.Println(no)
no = math.Trunc(-2.9)
fmt.Println(no)
no = math.Trunc(2)
fmt.Println(no)
}
Output:
1
-2
0
-2
2
