GoLang – Find Binary Representation – Float64bits() Function – Examples & Explanation

The syntax of Float64bits() function in Go Language is:

func Float64bits(x float64) uint64

Note: float64 is a data type in Go language which has IEEE-754 64-bit floating-point numbers. uint64 is the set of all unsigned 64-bit integers.

x – Where x is any Valid float64 Input value. This parameter is required.

If the x parameter is not a number (numeric value) Float64bits() function returns an error .
If there is no argument (x – input value) passes to the function, then the compiler will produce an error.

Float64bits() function will return the IEEE 754 binary representation of the given input(x – parameter).

package main

import "fmt"
import "math"

func main() {
	var x uint64
	x = math.Float64bits(2)
	fmt.Println(x)
} 

Output:

package main

import "fmt"
import "math"

func main() {
	var x uint64
	x = math.Float64bits(-17.6)
	fmt.Println(x)
}
