GoLang – Find Natural Logarithm – Log() Function – Examples & Explanation

The syntax of Log() function in Go Language is:

func Log(x float64) float64

Note: float64 is a data type in Go language which has IEEE-754 64-bit floating-point numbers.
Special cases are:
Log(+Inf) = +Inf
Log(0) = -Inf
Log(x < 0) = NaN
Log(NaN) = NaN

x – Where x is any Valid float64 Input value. This parameter is required.

If the x parameter is not a number (numeric value) Log() function returns an error .
If there is no argument (x – input value) passes to the function, then the compiler will produce an error.

Log() function will return the natural logarithm of the given input(x – parameters).

package main

import "fmt"
import "math"

func main() {
	var x float64
	x = math.Log(-5.39)
	fmt.Println(x)
} 

Output:
NaN

package main

import "fmt"
import "math"

func main() {
	var x float64
	x = math.Log(13.476)
	fmt.Println(x)
} 

Output:
2.6009103255443065

package main

import "fmt"
import "math"

func main() {
	var x float64
	x = math.Log(97)
	fmt.Println(x)
} 

Output:
