In Golang, the strconv package does not provide a direct method to convert a string to a complex number. However, you can achieve this by manually parsing the string and then converting it to a complex number. Here's an example:
package main
import (
"fmt"
"strconv"
"strings"
)
func main() {
str := "3+4i" // Example string representing a complex number
// Splitting the string into real and imaginary parts
parts := strings.Split(str, "+")
if len(parts) != 2 {
fmt.Println("Invalid complex number format")
return
}
// Parsing real and imaginary parts
realPart, err := strconv.ParseFloat(parts[0], 64)
if err != nil {
fmt.Println("Error parsing real part:", err)
return
}
imaginaryPart, err := strconv.ParseFloat(strings.TrimSuffix(parts[1], "i"), 64)
if err != nil {
fmt.Println("Error parsing imaginary part:", err)
return
}
// Creating the complex number
complexNum := complex(realPart, imaginaryPart)
fmt.Println(complexNum)
}
This example takes a string in the format "a+bi", splits it into real and imaginary parts, converts both parts to float64 using strconv.ParseFloat(), and finally creates a complex number using the complex() function.
Note that this code assumes that the format of the string is always in the form "a+bi". If you need to handle more complex formats, you might need to modify the parsing logic accordingly.
