Exp()

The Exp() function returns the value of e^x (e to the power of x), where x is the parameter.

Syntax

import "math"

value := math.Exp(number)

Where value is the value of e raised to the power of number, and where number is a variable of type float64.

Special cases:

• Exp(+Inf) returns +Inf
• Exp(NaN) returns NaN as well (Not a Number)

Example

The following code calculates the value of e to the power of 3, and prints the resulting value to the console.

package main

import (
  "fmt"
  "math"
)

func main() {
  result := math.Exp(math.Inf(1))
  fmt.Printf("%.1f\n", result)
}

The output will be:

+Inf
