The Go programming language uses the **`Inf`** function to generate an infinite value.

To use this function, you must import the `math` package in your file and access the `Inf` function within it using the `.` notation (`math.Inf`). Here, `Inf` is the actual function, while `math` is the Go package that stores the definition of this function.

# Function definition

The definition of the `Inf` function inside the `math` package is:


# Parameters
`Inf` function takes a single argument of `int` type.



# Return value

The `Inf` function returns a single infinite value of type `float64`. The sign of this infinite value will be the same as the sign of the argument.

> A special case is when the argument is zero, in which case the `Inf` function treats it as a positive number, i.e., it returns positive infinity.

# Examples

Here is a simple example that generates infinite values of different signs:

package main

import(
  "fmt" 
  "math"
) 

func main() {
  x := -233
	y := math.Inf(x)
	fmt.Print("The Inf function with the argument ",x, " returns: ", y,"\n")

  x = 233
	y = math.Inf(x)
	fmt.Print("The Inf function with the argument ",x, " returns: ", y)


} 

The `Inf` function always treats `0` as a positive number and so returns positive infinity if the argument is `0`: 

package main

import(
  "fmt" 
  "math"
) 

func main() {
  x := 0
	y := math.Inf(x)
	fmt.Print("The Inf function with the argument ",x, " returns: ", y,"\n")

} 

What is the Inf function in golang?

Go's Inf function in the math package generates infinite float64 values based on the sign of its int argument.
