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
