Exp() function is used to find the power of e in the form of e**x for the given input (x – parameter) in Go language.
The standard math package of Go programming language has Exp() function. The purpose of this function is to find the base-e exponential of x (e**x). Where e is called Euler’s number, named after the renowned mathematician Leonhard Euler.
Syntax of Exp() Function in Go Language
The syntax of
Note:
Special cases are:
Note: Very large values overflow to
Exp() function in Go Language is:1 | func Exp(x float64) float64 |
Note:
float64 is a data type in Go language which has IEEE-754 64-bit floating-point numbers.Special cases are:
Exp(+Inf) = +Inf
Exp(NaN) = NaNNote: Very large values overflow to
0 or +Inf. Very small values underflow to 1.
Parameters of Exp() 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) Exp() 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 Exp() Function in Go Language
Exp() function will return the e**x, the base-e exponential of x of the given input(x – parameters).
GoLang Exp() 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.Exp(0.369) fmt.Println(x) } |
Output:
