math.Inf() Function in Golang With Examples

Go language provides inbuilt support for basic constants and mathematical functions to perform operations on the numbers with the help of the math package. You can find positive infinity (if sign >= 0) or negative infinity (if sign < 0) with the help of the Inf() function provided by the math package. So, you need to add a math package in your program with the help of the import keyword to access the Inf() function. 
Syntax:

func Inf(sign int) float64

Example 1:

C

// Golang program to illustrate the
// math.Inf() Function
package main

import (
    "fmt"
    "math"
)

// Main function
func main() {

    // Finding positive infinity
    // and negative infinity
    // Using Inf() function
    res_1 := math.Inf(-1)
    res_2 := math.Inf(1)

    // Displaying the result
    fmt.Println("Result 1: ", res_1)
    fmt.Println("Result 2: ", res_2)

}

Output:

Result 1: -Inf
Result 2: +Inf

Example 2:

C

// Golang program to illustrate the
// math.Inf() Function
package main

import (
    "fmt"
    "math"
)

// Main function
func main() {

    // Finding positive infinity
    // and negative infinity
    // Using Inf() function
    nvalue := math.Inf(2)
    mvalue := math.Inf(-3)

    fmt.Println("Positive infinity: ", nvalue)
    fmt.Println("Negative infinity: ", mvalue)

}

Output:

Positive infinity:  +Inf
Negative infinity:  -Inf
