Here, We will learn how to get the greatest integer value of a number in go. We can get it by using Floor() function in math package in go golang.
Function prototype:
func Floor(no float64) float64
Return value:
Floor() function in math package returns
the greatest integer value less than or equal
to number.
Example with code:
package main
import (
"fmt"
"math"
)
func main() {
no := math.Floor(2.51)
fmt.Printf("%.1f\n", no)
no = math.Floor(2.39)
fmt.Printf("%.1f\n", no)
no = math.Floor(3.12)
fmt.Printf("%.1f\n", no)
no = math.Floor(-3.21)
fmt.Printf("%.1f\n", no)
}
Output:
2.0
2.0
3.0
-4.0
