Here, We will learn about Frexp() fucntion in math package in go.
Function prototype:
func Frexp(x float64) (fract float64, expo int)
Return value:
Frexp() function in math package breaks
x into a normalised fraction and an integral power of two.
It also returns fract and expo satisfying x == fract × 2**expo with the absolute value of fract in the interval [½, 1).
Example with code:
package main
import (
"fmt"
"math"
)
func main() {
fract, expo := math.Frexp(1)
fmt.Println(fract, expo)
fract, expo = math.Frexp(2)
fmt.Println(fract, expo)
fract, expo = math.Frexp(0.75)
fmt.Println(fract, expo)
fract, expo = math.Frexp(-2)
fmt.Println(fract, expo)
}
Output:
0.5 1
0.5 2
0.75 0
-0.5 2
