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
