math.Inf() Function in Golang With Examples Last Updated : 28 Apr, 2025 Summarize Comments Improve Suggest changes Share Like Article Like Report 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 Comment More infoAdvertise with us Next Article math.Inf() Function in Golang With Examples K Kirti_Mangal Follow Improve Article Tags : Go Language Golang-Math Similar Reads math.Jn() 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.
