math.SmallestNonzeroFloat32 Constant

The SmallestNonzeroFloat32 constant is an inbuilt constant of the math package which is used to get the smallest positive, non-zero value of float32 type.

The value of math.SmallestNonzeroFloat32 constants is 1.401298464324817070923729583289916131280e-45 or 0x1p-126 * 0x1p-23.

Syntax

float64 math.SmallestNonzeroFloat32

Parameters

• None

Return Value

The return type of math.SmallestNonzeroFloat32 constant is float64, it returns the smallest positive, non-zero value of float32 type.

Example 1

// Golang program to demonstrate the
// example of math.SmallestNonzeroFloat32 Constant

package main

import (
	"fmt"
	"math"
)

func main() {
	fmt.Printf("Type of math.SmallestNonzeroFloat32 is %T\n", math.SmallestNonzeroFloat32)
	fmt.Println("Value of math.SmallestNonzeroFloat32:", math.SmallestNonzeroFloat32)
}

Output:

Type of math.SmallestNonzeroFloat32 is float64
Value of math.SmallestNonzeroFloat32: 1.401298464324817e-45

Explanation:

In the above program, we imported the math package to use the math.SmallestNonzeroFloat32 constant, then printed the type and value of the math.SmallestNonzeroFloat32 constant.

Example 2

// Golang program to demonstrate the
// example of math.SmallestNonzeroFloat32 Constant

package main

import (
	"fmt"
	"math"
)

// creating function to
// return the value of SmallestNonzeroFloat32.
func getSmallestNonzeroFloat32() float64 {
	return math.SmallestNonzeroFloat32
}

func main() {
	fmt.Println("Value of math.SmallestNonzeroFloat32:", getSmallestNonzeroFloat32())
}

Output:

Value of math.SmallestNonzeroFloat32: 1.401298464324817e-45
