GoLang – Find Power of e in Form of e**x – Exp() Function – Examples & Explanation

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 Exp() function in Go Language is:

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) = NaN

Note: 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 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).
