Submitted by IncludeHelp, on August 31, 2021

math.Float32frombits()

The Float32frombits() function is an inbuilt function of the math package which is used to get the floating-point number corresponding to the IEEE 754 binary representation b, with the sign bit of b and the result in the same bit position. Where b is the given parameter.

It accepts a parameter (b) and returns the floating-point number corresponding to the IEEE 754 binary representation b.

Syntax

func Float32frombits(b uint32) float32

Parameters

• b : The value of uint32 type whose floating-point number corresponding to the IEEE 754 binary representation to be found.

Return Value

The return type of Float32frombits() function is a float32, it returns the floating-point number corresponding to the IEEE 754 binary representation of the given parameter.

Example 1

// Golang program to demonstrate the
// example of math.Float32frombits() Function

package main

import (
	"fmt"
	"math"
)

func main() {
	fmt.Println(math.Float32frombits(0))
	fmt.Println(math.Float32frombits(1084227584))
	fmt.Println(math.Float32frombits(3231711232))
	fmt.Println(math.Float32frombits(1093140480))
	fmt.Println(math.Float32frombits(3240624128))
	fmt.Println(math.Float32frombits(1008981770))
}

Output:

0
5
-5
10.5
-10.5
0.01

Example 2

// Golang program to demonstrate the
// example of math.Float32frombits() Function

package main

import (
	"fmt"
	"math"
)

func main() {
	var x uint32
	var Float32frombitsX float32

	x = 0
	Float32frombitsX = math.Float32frombits(x)
	fmt.Println("Float32frombits(", x, ") = ", Float32frombitsX)

	x = 1056964608
	Float32frombitsX = math.Float32frombits(x)
	fmt.Println("Float32frombits(", x, ") = ", Float32frombitsX)

	x = 1086324736
	Float32frombitsX = math.Float32frombits(x)
	fmt.Println("Float32frombits(", x, ") = ", Float32frombitsX)

	x = 3233808384
	Float32frombitsX = math.Float32frombits(x)
	fmt.Println("Float32frombits(", x, ") = ", Float32frombitsX)

	x = 3189348762
	Float32frombitsX = math.Float32frombits(x)
	fmt.Println("Float32frombits(", x, ") = ", Float32frombitsX)
}

Output:

Float32frombits( 0 ) =  0
Float32frombits( 1056964608 ) =  0.5
Float32frombits( 1086324736 ) =  6
Float32frombits( 3233808384 ) =  -6
Float32frombits( 3189348762 ) =  -0.15
