Here, We will learn how to check negative number in go. We can get it by using Signbit() function in math package in go golang.
Function prototype:
func Signbit(x float64) bool
Return value:
Signbit() function in math package returns
whether x is negative or negative zero.
Example with code:
package main
import (
"fmt"
"math"
)
func main() {
no := math.Signbit(1.2)
fmt.Println(no)
no = math.Signbit(-2.7)
fmt.Println(no)
no = math.Signbit(0.0)
fmt.Println(no)
no = math.Signbit(-2.9)
fmt.Println(no)
no = math.Signbit(2)
fmt.Println(no)
}
Output:
false
true
false
true
false
