complx.Polar() Function in Golang returns the absolute value r and phase θ of x. The phase θ will be in the range [-Pi, Pi].

Syntax:

func Polar(x complex128) (r, θ float64)

Here, x is a complex number.

Return Value: The return value is in the range [-Pi, Pi].

Example 1:




// Golang program to illustrate
// the complx.Polar() Function
  
package main
  
// importing fmt, math and math/cmplx
import (
"fmt"
"math"
"math/cmplx"
)
  
// Calling Main
func main() {
      
    // getting the r and theta value
    r, theta := cmplx.Polar(7i) 
      
    // calculate the value in Pi format.
    p := theta/math.Pi 
      
    // printing the values r and p.
    fmt.Printf("rValue: %.1f, pValue: %.1f*Pi", r, p) 
}


Output:

rValue: 7.0, pValue: 0.5*Pi

Example 2:




// Golang program to illustrate
// the complx.Polar() Function
  
package main
  
// importing fmt, math and math/cmplx
import (
"fmt"
"math"
"math/cmplx"
)
  
// Calling Main
func main() {
  
    // We can create a complex number like this also.   
    n := complex(5, 6)
      
    // getting the r and theta value of complex number 5 + 6i
    r, theta := cmplx.Polar(n)
      
    // calculate the value in Pi format.
    p := theta/math.Pi 
      
    // printing the values r and p.
    fmt.Printf("rValue: %.1f, pValue: %.1f*Pi", r, p) 
}


Output:

rValue: 7.8, pValue: 0.3*Pi
