complx.Exp() Function in Golang With Examples Last Updated : 28 Apr, 2020 Comments Improve Suggest changes Like Article Like Report complx.Exp() Function in Golang is used to returns e**x, the base-e exponential of x. Syntax: func Exp(x complex128) complex128 Here, x is the set of all complex numbers real as well as imaginary parts. Return Type: The return type of this function is a complex number. Example 1: C // Golang program to illustrate // the complx.Exp() Function package main // importing fmt and math/cmplx import ( "fmt" "math/cmplx" ) // Calling main method func main() { // using the function fmt.Printf("%.2f", cmplx.Exp(5 + 6i)) } Output: (142.50-41.47i) Example 2: C // Golang program to illustrate // the complx.Exp() Function package main // importing fmt and math/cmplx import ( "fmt" "math/cmplx" ) // Calling main method func main() { n := complex(7, 8) // using the function fmt.Printf("%.2f", cmplx.Exp(n)) } Output: (-159.56+1084.96i) Comment More infoAdvertise with us Next Article complx.Exp() Function in Golang With Examples P PranchalKatiyar Follow Improve Article Tags : Go Language Golang-Complex Similar Reads complx.Pow() Function in Golang With Examples complx.Pow() Function in Golang is used to find x**y, the base-x exponential of y. For this function, one need to import the "math/cmplx" package.
