GoLang – Find Binary Representation – Float32frombits() Function – Examples & Explanation

The syntax of Float32frombits() function in Go Language is:

func Float32frombits(x uint32) float32

Note: float32is the set of all IEEE-754 32-bit floating-point numbers and uint32 is the set of all unsigned 32-bit integers. With the range of 0 through 4294967295.

x – Where x is any Valid float32 Input value. This parameter is required.

If the x parameter is not a number (numeric value) Float32frombits() function returns an error .
If there is no argument (x – input value) passes to the function, then the compiler will produce an error.

Float32frombits() function will return the floating point number corresponding to the IEEE 754 binary representation of the given input(x – parameter).

package main

import "fmt"
import "math"

func main() {
	var x float32
	x = math.Float32frombits(3)
	fmt.Println(x)
}

Output:
4e-45

package main

import "fmt"
import "math"

func main() {
	var x float32
	x = math.Float32frombits(89)
	fmt.Println(x)
}

Output:
1.25e-43

package main

import "fmt"
import "math"

func main() {
	var x float32
	x = math.Float32frombits(4294967295)
	fmt.Println(x)
}

Output:
NaN
