math.MaxFloat32 Constant

The MaxFloat32 constant is an inbuilt constant of the math package which is used to get the largest finite value of float32 type.

The value of math.MaxFloat32 constants is 3.40282346638528859811704183484516925440e+38 or 0x1p127 * (1 + (1 - 0x1p-23)).

Syntax:

float64 math.MaxFloat32

Parameter(s):

• None

Return Value:

The return type of math.MaxFloat32 constant is float64, it returns the largest finite value of float32 type.

Example 1:

// Golang program to demonstrate the
// example of math.MaxFloat32 Constant

package main

import (
	"fmt"
	"math"
)

func main() {
	fmt.Printf("Type of math.MaxFloat32 is %T\n", math.MaxFloat32)
	fmt.Println("Value of math.MaxFloat32:", math.MaxFloat32)
}

Output:

Type of math.MaxFloat32 is float64
Value of math.MaxFloat32: 3.4028234663852886e+38

Explanation:

In the above program, we imported the math package to use the math.MaxFloat32 constant, then printed the type and value of the math.MaxFloat32 constant.

Example 2:

// Golang program to demonstrate the
// example of math.MaxFloat32 Constant

package main

import (
	"fmt"
	"math"
)

// creating function to
// return the value of MaxFloat32.
func getMaxFloat32() float64 {
	return math.MaxFloat32
}

func main() {
	fmt.Println("Value of math.MaxFloat32:", getMaxFloat32())
}

Output:

Value of math.MaxFloat32: 3.4028234663852886e+38
