Log() function is used to find the natural logarithm of the given input (x – parameter) in Go language. The standard math package of Go programming language has Log() function.
Syntax of Log() Function in Go Language
The syntax of Log() function in Go Language is:
1 | 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
Parameters of Log() Function in Go Language
x – Where x is any Valid float64 Input value. This parameter is required.
Error Handling
If the
If there is no argument (
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.
Return Value of Log() Function in Go Language
Log() function will return the natural logarithm of the given input(x – parameters).
GoLang Log() Function Example 1
1 2 3 4 5 6 7 8 9 10 | package main import "fmt" import "math" func main() { var x float64 x = math.Log(-5.39) fmt.Println(x) } |
Output:
NaN
GoLang Log() Function Example 2
1 2 3 4 5 6 7 8 9 10 | package main import "fmt" import "math" func main() { var x float64 x = math.Log(13.476) fmt.Println(x) } |
Output:
2.6009103255443065
GoLang Log() Function Example 3
1 2 3 4 5 6 7 8 9 10 | package main import "fmt" import "math" func main() { var x float64 x = math.Log(97) fmt.Println(x) } |
Output:
4.574710978503383
